  AUTHOR’S NOTE

  Woolly is a dramatic narrative account based on numerous interviews, multiple first-person sources, and hundreds of pages of articles. In some instances, settings have been changed, and certain descriptions and characters have been altered to protect privacy. I employ the technique of re-created dialogue, based on the recollection of participants who were there, various diaries and files, and newspaper accounts, doing my best to communicate the substance of these conversations, especially in scenes taking place years ago.

  PART ONE

  Very often, as I wander through life, I’ll get that old feeling that I’ve come back from the future, and I’m living in the past. And it’s a really horrible feeling.

  CHAPTER ONE

  Three thousand years ago

  WRANGEL ISLAND.

  An eighty-mile-wide swath of volcanic rock, gravel, and permafrost jutting out from the Arctic Ocean, ninety miles off the coast of Siberia, windswept and forbidding. Gray on gray on gray, a forgotten stretch of beach covered in a thick mist, the air heavy with the spray from waves crashing through the loose ice beyond the breakers.

  A little after 5:00 a.m., the calf opens his eyes.

  Even though his mother is only a few yards away, splayed out against a makeshift nest of dry reeds that she has gathered from the underbrush deeper toward the center of the island, the calf feels strangely alone. The rest of his herd—twenty-five strong, arranged along a matriarchal line that stretches back through three generations—has already begun a short pilgrimage down the coast. Being separated from the bulk of the herd feels unnatural. A mild illness has briefly kept his mother from engaging in the routines of survival on the island, so she’s stayed behind as the herd has set out to search for more sources of drinkable water and grazing. At less than a year old, the calf has remained with his mother, his familial bonds and youthful needs overcoming his developing social instincts. But neither nature nor nurture makes sitting around waiting for her to get back to her full energy any easier.

  The calf pushes himself to his feet, the thick muscles in his enormous legs trembling with the effort. His size already makes rising from the ground a bit of an ordeal. He weighed over two hundred pounds at birth and even then stood over three feet tall. Now, though he is far from fully grown, he weighs well over a thousand pounds.

  He shakes his head back and forth, shedding reeds and bits of snow and ice that gathered over him as he slept. His mother is still lying on her left side against the ground in front of him, her huge body rising and falling as each breath sends clouds of condensation through the frozen air. As big as the calf is, his mother is a veritable mountain, five, maybe six tons, and more than twice his height. It is no wonder that his kind often naps standing up. When they do sleep flat against the ground, it is usually for periods of no more than four to five hours.

  The calf watches his mother for a few minutes, then kicks the last bits of ice off his legs and starts forward down a gentle, gravelly slope that leads toward the beach.

  Each heavy step sends tremors up and down his body, as his huge feet compress and churn the frozen ground. The wind howls around him, pushing his tiny, round ears flat against the sides of his head, but he continues forward, his eyes searching the turned permafrost beneath him for bits of grass, moss, roots. As he nears the bottom of the slope, he starts to feel the spray from the waves that crash against the large volcanic rocks making up much of the coast; the water feels good against his body, the glistening, bluish drops beading against the long strands of thick red hair that cover most of his hide.

  Despite the wind, the icy water, the cold, the calf is not uncomfortable. Though it is a harsh environment, he and his herd are uniquely suited for it; in fact, for thousands of years, Wrangel Island has enabled the huge animals to survive and thrive.

  Even now, his is one of perhaps two dozen herds on the island. At one time, the super-herd numbered close to a thousand individuals, though in recent years it has dwindled to half that.

  Though the interrelated herds have always lived in proximity to various predators, it wasn’t claws and teeth that cut down the calf’s cousins, aunts, and uncles in recent years. The thinning of his kind was part of a natural process of adaptation. The world around him has changed, and his species has adjusted; smaller in number, leaner, but functioning. In this forgotten corner of the world, they have learned, survived.

  In fact, though the calf couldn’t possibly know, the isolated, icy nature of his island home is the only reason the herd still exists at all. A twist of fate, an accident of geography, a turn of weather: Six thousand years earlier, as the world had first begun to warm, the water surrounding Wrangel had risen—fifty feet or more—and cut off the island from the mainland. The calf’s ancestors, who had crossed over one herd at a time along an ice bridge during the colder months of the year, had found themselves trapped. Lost in time.

  Saved.

  While the calf’s super-herd adapted to its isolation on Wrangel, the rest of their species had died off around the world, over four thousand years ago. The five hundred or so individuals left on the island are all that remain. Split into familial units, close-knit, living in a symbiotic relationship with the island itself, they have lived four thousand years beyond their kind’s extinction.

  The calf finally reaches the bottom of the slope and is now less than a dozen yards from the water itself. The spray is even more palpable now, the frozen droplets pelting his face and hide like hail. It is time to head back up the slope toward his mother. Perhaps she is awake now and well enough to finally rejoin the herd, farther down the coast. He starts to shift his heavy body in the opposite direction, when something out on the water catches his attention.

  Cutting through the waves, slicing past the jagged chunks of ice and over the breaking foam—something the cub has never seen before. He stands frozen in place, staring at the long, cylindrical object, which his mind had no capacity to understand.

  Like a hollowed-out tree trunk, the object lies horizontal, moving forward on the ocean’s surface toward the beach—right in his direction.

  The calf takes a step back, then freezes again. Above the edges of the long object, he can now make out creatures, five or six of them, huddled together against the water’s spray. They are small and pale, covered in odd hides that aren’t hairy. And they are pointing at him.

  He watches as one of the creatures rises and lifts a thin wooden shaft tipped in razor-sharp bone high into the air. It is twice as long as the creature itself.

  The calf stares, too stunned to move. He does not know what these strange creatures are, or why they are heading to his beach. He cannot know that they have come to finish what the millennia of a warming world have not.

  The calf cannot know that he, his mother, his herd, are the last of his kind.

  After him, there will be no more.

  CHAPTER TWO

  Four years from today . . .

  CHERSKY, SAKHA REPUBLIC, SIBERIA.


  Justin Quinn was breathing hard as he trudged behind his long-legged Russian guide, trying not to trip over the patches of brush that randomly sprang from the fracturelike cracks speckling the frozen tundra beneath his snow boots. The boots weren’t his; he’d borrowed them from the locker room at the Northeast Science Center in Chersky four miles back, and though they were much warmer than the pair of hiking boots he’d brought with him from Boston, they were at least two sizes too big, the rough material reaching almost to his knees. Nor did it help that the parka he was wearing—also borrowed—was also oversized. The heavy synthetic fur of the hood kept getting into his mouth, and the sleeves went to his fingertips, making him look like a slovenly child, rather than a twenty-nine-year-old postdoc from the most prestigious university in the world.

  “It’s not much farther,” the Russian called back over his shoulder, his English tinged with such a heavy accent that Quinn had to concentrate to understand what the man was saying. “You’re doing much better than the last graduate student they sent me. He barely made it past the first mile marker.”

  Quinn wasn’t surprised. Even with the borrowed gear, every breath he took of the frozen air sent knifelike shards of pain through his lungs, and the skin of his face that was still exposed beneath that damn cocoon of fur was already numb. Quinn wasn’t a waif by any means; he’d been an athlete in high school and the various colleges he’d attended, before his academic interests made daily three-hour practices an untenable use of his time, but he wasn’t anywhere near fighting shape. Years sitting in various labs in Boston playing with test tubes, Petri dishes, and centrifuges would do that to you. And even if he’d been in peak condition, the terrain they had crossed since leaving the institute would have had him breathing hard.

  To call this stretch of geography “forbidding” would have been a gross understatement. Barely ninety miles from the Arctic Ocean, technically well within the geographic zone known as the Arctic Circle, the steppes surrounding the Northeast Science Center consisted mostly of windswept hills made of permafrost—ground that never thawed, up to thirteen feet deep in some places, covered by a thin layer of rocky soil—out of which sprouted various weeds, mosses, and lichen. Even though it was mid-April, the temperature hovered at a balmy –4 degrees Fahrenheit. And as frigid as it seemed, Quinn knew he was catching the region on a good day; the Republic of Sakha, the area of Siberia where the Science Station was located, was generally known for being the coldest section of the northern hemisphere. During the winter months, the temperature could drop as low as –76 degrees Fahrenheit.

  Stumbling forward over the ice-hardened ground, the wind biting at his cheeks, Quinn had a hard time believing anything could survive this far north. Then again, his Russian guide didn’t seem to mind the cold; in fact, he seemed to be moving faster the farther away they were from the relative comforts of the Science Station. Before he’d first packed up and headed into the Russian wilderness, Quinn had been told that his guide had been living exclusively at the station for more than two decades. In fact, the Russian and his family had secluded themselves in this stretch of harsh ecology to such a degree, some might have questioned their sanity. But that was often the case with the brilliant and the obsessed.

  “You see, we are just about there.”

  The Russian pointed a dozen yards ahead, toward the edge of what appeared to be a large, fenced-in enclosure. About ten feet high and made of a sturdy, chain-linked metal, the fence ran half the length of a football field in either direction. As Quinn continued to trudge closer, he saw at least a dozen shapes on the other side of the links. Animals, standing in groups of three and four, seemingly immune to the cold and the wind.

  Quinn assumed they were horses. At least they were horse shaped. But they were covered in thick brown fur and were muscled and stocky. They were not quite as short as a Shetland pony, but smaller than the horses Quinn had seen in America.

  “What are they?” he asked, as he trailed the Russian, who was walking parallel to the fence. “I don’t think I’ve ever seen anything like them before.”

  “Yakutian horses. We have nearly two dozen now. The last shipment came in three months ago and they’ve acclimated quite well. This is temperate for them, actually. In fact, they’ve even started to breed.”

  “Wow,” Quinn managed to say. He nearly tripped over a jagged piece of ice sticking up through the middle of a bed of frosted moss, but caught himself as they continued toward the far corner of the enclosure.

  “Yes, wow.” A very old breed, Yakutian horses evolved to live in the cold of the Yakut region, where they can locate vegetation that is under deep snow to graze on.

  The Russian pointed to his right, in the direction of another fenced enclosure, a few dozen yards away.

  “Over there, we have a group of North American bison that were shipped over last year. Beyond that, there’s a group of reindeer from Finland. Most of them were in pretty poor shape, but much cheaper than the bison. Hopefully the more persuasive our data become, the easier it will be to gather more specimens.”

  They’d reached the far corner of the enclosure, moving close enough that Quinn could have taken off a glove, reached out, and touched the metal links, if he hadn’t been worried about losing a finger to frostbite.

  “From what I’ve read, the data’s beyond persuasive.”

  “Here you don’t need to read, you can simply look and see for yourself.”

  The Russian pointed at the ground where the furry, stocky horses were grazing. Then toward the ground beneath Quinn’s giant boots. Quinn didn’t have to be a scientist to notice the clear difference: Outside the enclosure, little life beyond sparse moss and lichen was growing, but within the enclosure, where the Yakutian horses were huddled, the ground was covered in patches of thick, green grass.

  “When we get enough animals and take away the fences, the data will become even more extreme.”

  Quinn would have whistled, but his lips were nearly frozen. He knew, from his pretrip reading, that it wasn’t just the handful of animal enclosures at the core of the Russian’s rapidly expanding data set. Yakutian horses, bison, reindeer—the resettled animals were just one facet of the scientist’s ambitious experiment. The Russian’s team—beginning with his father, the true genius behind the experiment—had been working the acres of land around Chersky for decades now, with tools ranging from repurposed bulldozers with heavy, spiked treads, wheeled pile drivers that could pound the ground with precise, incredible pressure at the push of a button, to a surplus issue, World War II–era tank they had purchased from the Russian government in Yakutsk and driven several hundred miles to Chersky.

  Between the animals, the construction machinery, and the tank, they’d managed to accomplish something that many scientists might have thought impossible: Beneath the layer of grass within the various enclosures—the controlled test environments—they’d lowered the permafrost ground temperature by an average of fifteen degrees.

  Quinn wasn’t a climatologist—he was actually a student of biology, with a background in genetic engineering—but even he knew these numbers were staggering; more than that, they were important.

  Important enough to inspire him to take a trip halfway around the world.

  “When we take away the fences,” the Russian continued, without slowing his pace, “it will be like turning back time ten thousand years. Specimens will become herds. A repopulation.”

  “And what about predators?” Quinn asked, as they passed the edge of the enclosure and started slowly to ascend a hill of permafrost. “I assume they were once part of the history of this place?”

  “An important part, yes. Arctic wolves, polar bears. Before that, saber-toothed tigers.”

  “Saber-toothed tigers?”

  “The predators and the herbivores lived side by side. In fact, the predators helped the herbivores to thrive. They were territorial, and protected their herds from encroaching competitors. They also picked off the sick and weak. It was an im
portant balance. Until we came along.”

  Quinn knew where the story went from there. As the last ice age ended, human populations moved northward. Hunting parties decimated the native populations of herbivores and predators. Though the science was still a bit controversial, the Russian experiments—the resettled animals, the tank turning over the soil, the pile drivers—were meant to provide proof that it wasn’t just the changing environment that had caused the mass extinctions. In large part, it was the other way around.

  “At first, we were like every other predator in this place. We hunted what we needed. But we never get full. We never stop hunting. We aren’t just another predator—we are the Apex Predator.”

  The Russian looked back at him, as they reached the top of the slow rise. Quinn could see past the Russian’s shoulders; ahead of them rose another fence, at least twice as high as the Yakutian horse enclosure. It was also made of metal, but this fence was much thicker, and topped in curls of barbed wire. It took Quinn a full minute of breathing hard to realize—this fence wasn’t built to keep predators out. It was built to keep something in.

  The Russian strolled forward, toward a chain-link door built into a section of the fence directly in front of them. There was an electronic keypad halfway up the door, covered in Cyrillic letters. The Russian punched six of the keys in sequence, and they heard a metallic whir, electronic tumblers falling into place. Then the door swung inward. The Russian gestured for Quinn to step through.

  “Is this safe?” Quinn asked.

  “You don’t sound much like an Apex Predator.”

  Quinn swallowed, hard.

  “Actually, I’m a vegan.”

  The Russian laughed.

  “It’s perfectly safe. I promise, no saber-toothed tigers. Nothing but herbivores.”

  The Russian waited for Quinn to go through the open doorway first, then followed behind. Quinn found himself standing at the top of a long incline, looking down at an expanse of steppe similar to the four miles he’d just hiked—but, beginning a dozen yards ahead of him, much of the moss and lichen had been replaced by thick, green grass. Something had been turning this topsoil with enough regularity to make a real, significant difference. From the size of the area within the fencing, Quinn knew it had to be something much bigger than a World War II tank.
