Praise for

After the Fall, Before the Fall, During the Fall

“An ecological apocalypse so real that it’s like a three-dimensional object that can be viewed from all sides.”

—Ted Kosmatka, author of
The Helix Game
The Ascendant

“Nancy Kress displays all her usual strengths in
After the Fall, Before the Fall, During the Fall
: strong plotting, fast-paced action, complex and interesting characters, thought-provoking speculation. But there’s something more here: a beautiful meditation on the fate of the earth, an elegy, a warning—and a glimpse of hope.”

—Lisa Goldstein, author of
The Red Magician
The Uncertain Places

“This is Nancy Kress in top form, but more importantly, this is SF done right. Here are big ideas about the environment and the future of humanity, married to an intimate story of family, community, and motherhood. With aliens and time travel to boot! I don’t know of another writer who balances the global and the personal with such skill. I inhaled this story, and was sorry for it to end.”

—Daryl Gregory, author of
The Devil’s Alphabet

“This story, of the terrible choices people must make in the face of ecological catastrophe, asks wrenching questions—
What does it take to remain human? What is survival worth?
—and answers with the authority that Kress always brings to bear on both science and humanity.”

—Nicola Griffith, author of
Slow River

“The book is typical Kress, which means impossible to put down. A gripping tale of human survival.”

—Jack McDevitt, author of
Infinity Beach

After the Fall, Before the Fall, During the Fall
is the coming-of-age story for the human race. Nancy Kress has written a chillingly plausible tale of the end of the world.”

—Mary Robinette Kowal, author of
Shades of Milk and Honey

For Maura, my scientific advisor

 “We see in these facts some deep organic bond, prevailing throughout space and time. . . . This bond, on my theory, is simple inheritance.”

—Charles Darwin,
The Origin of Species

I: S minus 10.5 months


The publication party was held in the dean’s office, which was supposed to be an honor. Oak-paneled room, sherry in little glasses, small-paned windows facing the quad—the room was trying hard to be a Commons someplace like Oxford or Cambridge, a task for which it was several centuries too late. The party was trying hard to look festive. Marianne’s colleagues, except for Evan and the dean, were trying hard not to look too envious, or at their watches.

“Stop it,” Evan said at her from behind the cover of his raised glass.

“Stop what?”

“Pretending you hate this.”

“I hate this,” Marianne said.

“You don’t.”

He was half right. She didn’t like parties but she was proud of her paper, which had been achieved despite two years of gene sequencers that kept breaking down, inept graduate students who contaminated samples with their own DNA, murmurs of “Lucky find” from Baskell, with whom she’d never gotten along. Baskell, an old-guard physicist, saw her as a bitch who refused to defer to rank or back down gracefully in an argument. Many people, Marianne knew, saw her as some variant of this. The list included two of her three grown children.

Outside the open casements, students lounged on the grass in the mellow October sunshine. Three girls in cut-off jeans played Frisbee, leaping at the blue flying saucer and checking to see if the boys sitting on the stone wall were watching. Feinberg and Davidson, from Physics, walked by, arguing amiably. Marianne wished she were with them instead of at her own party.

“Oh God,” she said to Evan, “Curtis just walked in.”

The president of the university made his ponderous way across the room. Once he had been a historian, which might be why he reminded Marianne of Henry VIII. Now he was a campus politician, as power-mad as Henry but stuck at a second-rate university where there wasn’t much power to be had. Marianne held against him not his personality but his mind; unlike Henry, he was not all that bright. And he spoke in clichés.

“Dr. Jenner,” he said, “congratulations. A feather in your cap, and a credit to us all.”

“Thank you, Dr. Curtis,” Marianne said.

“Oh, ‘Ed,’ please.”

“Ed.” She didn’t offer her own first name, curious to see if he remembered it. He didn’t. Marianne sipped her sherry.

Evan jumped into the awkward silence. “I’m Dr. Blanford, visiting post-doc,” he said in his plummy British accent. “We’re all so proud of Marianne’s work.”

“Yes! And I’d love for you to explain to me your innovative process, ah, Marianne.”

He didn’t have a clue. His secretary had probably reminded him that he had to put in an appearance at the party:
Dean of Science’s office, 4:30 Friday, in honor of that publication by Dr. Jenner in
—quick look at e-mail—
very prestigious, none of our scientists has published there before
. . . .

“Oh,” Marianne said as Evan poked her discreetly in the side:
Play nice!
“it wasn’t so much an innovation in process as unexpected results from known procedures. My assistants and I discovered a new haplogroup of mitochondrial DNA. Previously it was thought that
Homo sapiens
consisted of thirty haplogroups, and we found a thirty-first.”

“By sequencing a sample of contemporary genes, you know,” Evan said helpfully. “Sequencing and verifying.”

Anything said in upper-crust British automatically sounded intelligent, and Dr. Curtis looked suitably impressed. “Of course, of course. Splendid results. A star in your crown.”

“It’s yet another haplogroup descended,” Evan said with malicious helpfulness, “from humanity’s common female ancestor 150,000 years ago. ‘Mitochondrial Eve.’”

Dr. Curtis brightened. There had been a TV program about Mitochondrial Eve, Marianne remembered, featuring a buxom actress in a leopard-skin sarong. “Oh, yes! Wasn’t that—”

“I’m sorry, you can’t go in there!” someone shrilled in the corridor outside the room. All conversation ceased. Heads swiveled toward three men in dark suits pushing their way past the knot of graduate students by the door. The three men wore guns.

Another school shooting
, Marianne thought,
where can I

“Dr. Marianne Jenner?” the tallest of the three men said, flashing a badge. “I’m Special Agent Douglas Katz of the FBI. We’d like you to come with us.”

Marianne said, “Am I under arrest?”

“No, no, nothing like that. We are acting under direct order of the president of the United States. We’re here to escort you to New York.”

Evan had taken Marianne’s hand—she wasn’t sure just when. There was nothing romantic in the handclasp, nor anything sexual. Evan, twenty-five years her junior and discreetly gay, was a friend, an ally, the only other evolutionary biologist in the department and the only one who shared Marianne’s cynical sense of humor.
“Or so we thought,”
they said to each other whenever any hypothesis proved wrong.
Or so we thought
. . . . His fingers felt warm and reassuring around her suddenly icy ones.

“Why am I going to New York?”

“I’m afraid we can’t tell you that. But it is a matter of national security.”

What possible reason—?”

Special Agent Katz almost, but not quite, hid his impatience at her questions. “I wouldn’t know, ma’am. My orders are to escort you to UN Special Mission Headquarters in Manhattan.”

Marianne looked at her gaping colleagues, at the wide-eyed grad students, at Dr. Curtis, who was already figuring how this could be turned to the advantage of the university. She freed her hand from Evan’s, and managed to keep her voice steady.

“Please excuse me, Dr. Curtis, Dean. It seems I’m needed for something connected with . . . with the aliens.”


One more time, Noah Jenner rattled the doorknob to the apartment. It felt greasy from too many unwashed palms, and it was still locked. But he knew that Emily was in there. That was the kind of thing he was always, somehow, right about. He was right about things that didn’t do him any good.

“Emily,” he said softly through the door, “please open up.”


“Emily, I have nowhere else to go.”


“I’ll stop, I promise. I won’t do sugarcane ever again.”

The door opened a crack, chain still in place, and Emily’s despairing face appeared. She wasn’t the kind of girl given to dramatic fury, but her quiet despair was even harder to bear. Not that Noah didn’t deserve it. He knew he did. Her fair hair hung limply on either side of her long, sad face. She wore the green bathrobe he liked, with the butterfly embroidered on the left shoulder.

“You won’t stop,” Emily said. “You can’t. You’re an addict.”

“It’s not an addictive drug. You know that.”

“Not physically, maybe. But it is for you. You won’t give it up. I’ll never know who you really are.”


“I’m sorry, Noah. But—go away.” She closed and relocked the door.

Noah stood slumped against the dingy wall, waiting to see if anything else would happen. Nothing did. Eventually, as soon as he mustered the energy, he would have to go away.

Was she right? Would he never give up sugarcane? It wasn’t that it delivered a high: it didn’t. No rush of dopamine, no psychedelic illusions, no out-of-body experiences, no lowering of inhibitions. It was just that on sugarcane, Noah felt like he was the person he was supposed to be. The problem was that it was never the same person twice. Sometimes he felt like a warrior, able to face and ruthlessly defeat anything. Sometimes he felt like a philosopher, deeply content to sit and ponder the universe. Sometimes he felt like a little child, dazzled by the newness of a fresh morning. Sometimes he felt like a father (he wasn’t), protective of the entire world. Theories said that sugarcane released memories of past lives, or stimulated the collective unconscious, or made temporarily solid the images of dreams. One hypothesis was that it created a sort of temporary, self-induced Korsakoff’s syndrome, the neurological disorder in which invented selves seem completely true. No one knew how sugarcane really acted on the brain. For some people, it did nothing at all. For Noah, who had never felt he fit in anywhere, it gave what he had never had: a sense of solid identity, if only for the hours that the drug stayed in his system.

The problem was, it was difficult to hold a job when one day you were nebbishy, sweet-natured Noah Jenner, the next day you were Attila the Hun, and two days later you were far too intellectual to wash dishes or make change at a convenience store. Emily had wanted Noah to hold a job. To contribute to the rent, to scrub the floor, to help take the sheets to the laundromat. To be an adult, and the same adult every day. She was right to want that. Only—

He might be able to give up sugarcane and be the same adult, if only he had the vaguest idea who that adult was. Which brought him back to the same problem—he didn’t fit anywhere. And never had.

Noah picked up the backpack in which Emily had put his few belongings. She couldn’t have left it in the hallway for very long or the backpack would have already been stolen. He made his way down the three flights from Emily’s walk-up and out onto the streets. The October sun shone warmly on his shoulders, on the blocks of shabby buildings, on the trash skirling across the dingy streets of New York’s lower East Side. Walking, Noah reflected bitterly, was one thing he could do without fitting in. He walked blocks to Battery Park, that green oasis on the tip of Manhattan’s steel canyons, leaned on a railing, and looked south.

He could just make out the
, floating in New York Harbor. Well, no, not the
itself, but the shimmer of light off its energy shield. Everybody wanted that energy shield, including his sister Elizabeth. It kept everything out, short of a nuclear missile. Maybe that, too: so far nobody had tried, although in the two months since the
had floated there, three different terrorist groups had tried other weapons. Nothing got through the shield, although maybe air and light did. They must, right? Even aliens needed to breathe.

When the sun dropped below the horizon, the glint off the floating embassy disappeared. Dusk was gathering. He would have to make the call if he wanted a place to sleep tonight. Elizabeth or Ryan? His brother wouldn’t yell at him as much, but Ryan lived upstate, in the same little Hudson River town as their mother’s college, and Noah would have to hitchhike there. Also, Ryan was often away, doing field work for his wildlife agency. Noah didn’t think he could cope with Ryan’s talkative, sticky-sweet wife right now. So it would have to be Elizabeth.

He called his sister’s number on his cheap cell. “Hello?” she snapped.
Born angry,
their mother always said of Elizabeth. Well, Elizabeth was in the right job, then.

“Lizzie, it’s Noah.”


“Yes. I need help. Can I stay with you tonight?” He held the cell away from his ear, bracing for her onslaught.
Shiftless, lazy, directionless
. . . . When it was over, he said, “Just for tonight.”

They both knew he was lying, but Elizabeth said, “Come on then,” and clicked off without saying good-bye.

If he’d had more than a few dollars in his pocket, Noah would have looked for a sugarcane dealer. Since he didn’t, he left the park, the wind pricking at him now with tiny needles, and descended to the subway that would take him to Elizabeth’s apartment on the upper West Side.


The FBI politely declined to answer any of Marianne’s questions. Politely, they confiscated her cell and iPad and took her in a sleek black car down Route 87 to New York, through the city to lower Manhattan, and out to a harbor pier. Gates with armed guards controlled access to a heavily fortified building at the end of the pier. Politely, she was searched and fingerprinted. Then she was politely asked to wait in a small windowless room equipped with a few comfortable chairs, a table with coffee and cookies, and a wall-mounted TV tuned to CNN. A news show was covering weather in Florida.

The aliens had shown up four months ago, their ship barreling out from the direction of the sun, which had made it harder to detect until a few weeks before arrival. At first, in fact, the ship had been mistaken for an asteroid and there had been panic that it would hit Earth. When it was announced that the asteroid was in fact an alien vessel, panic had decreased in some quarters and increased in others. A ship? Aliens? Armed forces across the world mobilized. Communications strategies were formed, and immediately hacked by the curious and technologically sophisticated. Seven different religions declared the end of the world. The stock and bond markets crashed, rallied, soared, crashed again, and generally behaved like a reed buffeted by a hurricane. Governments put the world’s top linguists, biologists, mathematicians, astronomers, and physicists on top-priority standby. Psychics blossomed. People rejoiced and feared and prayed and committed suicide and sent up balloons in the general direction of the moon, where the alien ship eventually parked itself in orbit.

Contact was immediate, in robotic voices that were clearly mechanical, and in halting English that improved almost immediately. The aliens, dubbed by the press “Denebs” because their ship came from the general direction of that bright, blue-white star, were friendly. The xenophiles looked smugly triumphant. The xenophobes disbelieved the friendliness and bided their time. The aliens spent two months talking to the United Nations. They were reassuring; this was a peace mission. They were also reticent. Voice communication only, and through machines. They would not show themselves: “Not now. We wait.” They would not visit the International Space Station, nor permit humans to visit their ship. They identified their planet, and astronomers found it once they knew where to look, by the faintly eclipsed light from its orange-dwarf star. The planet was in the star’s habitable zone, slightly larger than Earth but less dense, water present. It was nowhere near Deneb, but the name stuck.

After two months, the aliens requested permission to build what they called an embassy, a floating pavilion, in New York Harbor. It would be heavily shielded and would not affect the environment. In exchange, they would share the physics behind their star drive, although not the engineering, with Earth, via the Internet. The UN went into furious debate. Physicists salivated. Riots erupted, pro and con, in major cities across the globe. Conspiracy theorists, some consisting of entire governments, vowed to attack any Deneb presence on Earth.

The UN finally agreed, and the structure went into orbit around Earth, landed without a splash in the harbor, and floated peacefully offshore. After landing, it grew wider and flatter, a half-dome that could be considered either an island or a ship. The U.S. government decided it was a ship, subject to maritime law, and the media began capitalizing and italicizing it: the
. Coast Guard craft circled it endlessly; the U.S. Navy had ships and submarines nearby. Airspace above was a no-fly zone, which was inconvenient for jets landing at New York’s three big airports. Fighter jets nearby stayed on high alert.

Nothing happened.

For another two months the aliens continued to talk through their machines to the UN, and only to the UN, and nobody ever saw them. It wasn’t known whether they were shielding themselves from Earth’s air, microbes, or armies. The
was surveilled by all possible means. If anybody learned anything, the information was classified except for a single exchange:

Why are you here?

To make contact with humanity. A peace mission.

A musician set the repeated phrases to music, a sly and humorous refrain, without menace. The song, an instant international sensation, was the opening for playfulness about the aliens. Late-night comics built monologues around supposed alien practices. The
became a tourist attraction, viewed through telescopes, from boats outside the Coast Guard limit, from helicopters outside the no-fly zone. A German fashion designer scored an enormous runway hit with “the Deneb look,” despite the fact that no one knew how the Denebs looked. The stock market stabilized as much as it ever did. Quickie movies were shot, some with Deneb allies and some with treacherous Deneb foes who wanted our women or gold or bombs. Bumper stickers proliferated like kudzu: I BRAKE FOR DENEBS. EARTH IS FULL ALREADY—GO HOME. DENEBS DO IT INVISIBLY. WILL TRADE PHYSICS FOR FOOD.

The aliens never commented on any of it. They published the promised physics, which only a few dozen people in the world could understand. They were courteous, repetitive, elusive.
Why are you here? To make contact with humanity. A peace mission.

Marianne stared at the TV, where CNN showed footage of disabled children choosing Halloween costumes. Nothing about the discussion, the room, the situation felt real. Why would the aliens want to talk to her? It had to be about her paper, nothing else made sense. No, that didn’t make sense either.

“—donated by a network of churches from five states. Four-year-old Amy seizes eagerly on the black-cat costume, while her friend Kayla chooses—”

Her paper was one of dozens published every year on evolutionary genetics, each paper adding another tiny increment to statistical data on the subject. Why this one? Why her? The UN Secretary-General, various presidents and premiers, top scientists—the press said they all talked to the Denebs from this modern fortress, through (pick one) highly encrypted devices that permitted no visuals, or one-way visuals, or two-way visuals that the UN was keeping secret, or not at all and the whole alien-human conversation was invented. The
, however, was certainly real. Images of it appeared on magazine covers, coffee mugs, screen savers, tee shirts, paintings on velvet, targets for shooting ranges.

Marianne’s daughter Elizabeth regarded the aliens with suspicion, but then, Elizabeth regarded everyone with suspicion. It was one reason she was the youngest Border Patrol section leader in the country, serving on the New York Task Force along with several other agencies. She fit right in with the current American obsession with isolationism as an economic survival strategy.

Ryan seldom mentioned the aliens. He was too absorbed in his career and his wife.

And Noah—did Noah, her problem child, even realize the aliens were here? Marianne hadn’t seen Noah in months. In the spring he had gone to “try life in the South.” An occasional e-mail turned up on her phone, never containing much actual information. If Noah was back in New York, he hadn’t called her yet. Marianne didn’t want to admit what a relief that was. Her child, her baby—but every time they saw each other, it ended in recriminations or tears.

And what was she doing, thinking about her children instead of the aliens? Why did the ambassador want to talk to her? Why were the Denebs here?

To make contact with humanity. A peace mission. . . .

“Dr. Jenner?”

“Yes.” She stood up from her chair, her jaw set. Somebody better give her some answers, now.

The young man looked doubtfully at her clothes, dark jeans and a green suede blazer ten years old, her standard outfit for faculty parties. He said, “Secretary Desai will join you shortly.”

Marianne tried to let her face show nothing. A few moments later Vihaan Desai, Secretary-General of the United Nations, entered the room, followed by a security detail. Tall, elderly, he wore a sky-blue kurta of heavy, richly embroidered silk. Marianne felt like a wren beside a peacock. Desai held out his hand but did not smile. Relations between the United States and India were not good. Relations between the United States and everybody were not good, as the country relentlessly pursued its new policy of economic isolationism in an attempt to protect jobs. Until the Denebs came, with their cosmos-shaking distraction, the UN had been thick with international threats. Maybe it still was.

“Dr. Jenner,” Desai said, studying her intently, “it seems we are both summoned to an interstellar conference.” His English, in the musical Indian accent, was perfect. Marianne remembered that he spoke four languages.

She said, “Do you know why?”

Her directness made him blink. “I do not. The Deneb ambassador was insistent but not forthcoming.”

And does humanity do whatever the ambassador insists on? Marianne did not say this aloud. Something here was not adding up. The Secretary-General’s next words stunned her.

“We, plus a few others, are invited aboard the
. The invitation is dependent upon your presence, and upon its immediate acceptance.”

“Aboard . . . aboard the

“It seems so.”

“But nobody has ever—”

“I am well aware of that.” The dark, intelligent eyes never left her face. “We await only the other guests who happen to be in New York.”

“I see.” She didn’t.

Desai turned to his security detail and spoke to them in Hindi. An argument began. Did security usually argue with their protectees? Marianne wouldn’t have thought so, but then, what did she know about UN protocol? She was out of her field, her league, her solar system. Her guess was that the Denebs were not allowing bodyguards aboard the
, and that the security chief was protesting.

Evidently the Secretary-General won. He said to her, “Please come,” and walked with long strides from the room. His kurta rustled at his ankles, shimmering sky. Not intuitive, Marianne could nonetheless sense the tension coming off him like heat. They went down a long corridor, trailed by deeply frowning guards, and down an elevator. Very far down—did the elevator go under the harbor? It must. They exited into a small room already occupied by two people, a man and a woman. Marianne recognized the woman: Ekaterina Zaytsev, the representative to the UN from the Russian Federation. The man might be the Chinese representative. Both looked agitated.

Desai said in English, “We await only—ah, here they are.”

Two much younger men practically blew into the room, clutching headsets. Translators. They looked disheveled and frightened, which made Marianne feel better. She wasn’t the only one battling an almost overwhelming sense of unreality. If only Evan could be here, with his sardonic and unflappable Britishness.
“Or so we thought. . . .”

No. Neither she nor Evan had ever thought of this.

“The other permanent members of the Security Council are unfortunately not immediately available,” Desai said. “We will not wait.”

Marianne couldn’t remember who the other permanent members were. The UK, surely, but who else? How many? What were they doing this October dusk that would make them miss first contact with an alien species? Whatever it was, they had to regret it the rest of their lives.

Unless, of course, this little delegation never returned—killed or kidnapped or eaten. No, that was ridiculous. She was being hysterical. Desai would not go if there were danger.

Of course he would. Anyone would. Wouldn’t they? Wouldn’t she? Nobody, she suddenly realized, had actually asked her to go on this mission. She’d been ordered to go. What if she flat-out refused?

A door opened at the far end of the small room, voices spoke from the air about clearance and proceeding, and then another elevator. The six people stepped into what had to be the world’s most comfortable and unwarlike submarine, equipped with lounge chairs and gold-braided officers.

A submarine. Well, that made sense, if plans had been put in place to get to the
unobserved by press, tourists, and nut jobs who would blow up the alien base if they could. The Denebs must have agreed to some sort of landing place or entryway, which meant this meeting had been talked of, planned for, long before today. Today was just the moment the aliens had decided to put the plan into practice. Why? Why so hastily?

“Dr. Jenner,” Desai said, “in the short time we have here, please explain your scientific findings to us.”

None of them sat in the lounge chairs. They stood in a circle around Marianne, who felt none of the desire to toy with them as she had with Dr. Curtis at the college. Where were her words going, besides this cramped, luxurious submarine? Was the president of the United States listening, packed into the situation room with whoever else belonged there?

“My paper is nothing startling, Mr. Secretary-General, which is why this is all baffling to me. In simple terms—” she tried to not be distracted by the murmuring of the two translators into their mouthpieces “—all humans alive today are the descendants of one woman who lived about 150,000 years ago. We know this because of mitochondrial DNA, which is not the DNA from the nucleus of the cell but separate DNA found in small organelles called mitochondria. Mitochondria, which exist in every cell of your body, are the powerhouses of the cell, producing energy for cellular functions. Mitochondrial DNA does not undergo recombination and is not found in a sperm cell after it reaches the egg. So the mitochondrial DNA is passed down unchanged from a mother to all her children.”
