"I had to promise we’d come back in one piece. Oh, and…"

"Yes?"

He bent so only she could hear. "I had to take Snagtooth with me."

The three mammoths set off at midnight. There was a layer of cloud above, but the pale orange sun hung above the horizon in a clear strip of sky.

Heading south, the mammoths walked slowly, frequently pausing to pass dung and to feed. Despite Silverhair’s urgent wish to return to Lop-ear’s bones, Eggtusk insisted they eat their fill. They were coming into the richest season of the year, the time when the mammoths must lay in their reserves of fat, without which they cannot survive the next winter. As Eggtusk said to Silverhair, "I’d lick out the crusty lichen from between Kilukpuk’s pus-ridden toes before I’d let you starve yourself to death. What use would that be to Lop-ear, or any of us? Eh?"

So under his coaxing and scolding, she cropped the grass and flowers, and the fresh buds of the dwarf willows whose branches barely grew high enough to cover her toes.

Snagtooth continued to be a problem. A growing one, in fact.

Though the stump of her smashed tusk had healed over — a great blood-red scar had formed over the gaping socket — Silverhair saw her banging her head against rock outcrops, as if trying to shake loose the pain of the tusk root. Snagtooth had a great deal of difficulty sleeping; even the back-and-forth movement of her jaw when eating seemed to hurt her.

And Snagtooth was not one to suffer in silence.

She complained, snapped, and refused to do her fair share of digging, even expecting Silverhair and Eggtusk to find her rich clumps of grass and rip them out and carry them to her ever-open mouth. Silverhair could see why Owlheart had taken the opportunity to send her away from Foxeye and the calves for a while.

"I put up with it because I can see she is suffering," grumbled Eggtusk to Silverhair. "Perhaps she has an abscess."

If so, it was bad news; there was no way to treat such an agonizing collection of poison in the mouth, and Snagtooth would simply have to hope it cleared up of its own accord. If it didn’t, it could kill her.

Poor Eggtusk, meanwhile, was having his own trouble with warble flies. Silverhair could see maggots dropping out of red-rimmed craters in his skin, heading for the ground to pupate. Unnoticed, the flies must have laid eggs in his fur last summer. The eggs quickly hatched and the maggots burrowed into Eggtusk’s tissue, migrating around the body before coming to rest near the skin of his back. Here they would have continued to grow through the winter and spring in a cavity filled with pus and blood, breathing through an airhole gnawed in the skin. The eruption of the full-grown larvae was a cause of intense irritation to Eggtusk, who, despite his colorful cursing, was helpless to do anything about it.

Meanwhile the season bloomed around them. As the height of the brief summer approached, the tundra exploded with activity, as plants, animals, birds, and insects sought to complete the crucial stages of their annual lives in this brief respite from the grip of winter. The flowers of the tundra opened: white mountain avens, yellow poppies, white heather, crimson, yellow, red, white and purple saxifrage, lousewort, pink primulas, even the orange marigolds. All these flowers had started their cycle of growth as soon as the snow melted. And birds were everywhere. Snow buntings caught crane flies to feed their chicks. Skuas hunted the fledglings of turnstones and sanderlings. As she passed a cliff, Silverhair saw barnacle geese fledglings taking their first tentative steps from their parents’ nests far above. That meant jumping. The chicks’ stubby wings flapped uselessly, and they fell to the bottom of the cliff. Many chicks died from the fall, and others, trapped in scree, were snapped up by the eager jaws of Arctic foxes.

The silence of the winter was long gone. The air was filled with birdsong — larks and plovers, the haunting calls of loons, irritable jaeger cries — and the buzz of insects, the bark and howls of foxes and wolves. All of it was laced with an occasional agonized scream as some predator attained its goal.

It was a furious chorus of mating and death.

Through the flat, teeming landscape, Silverhair and the others walked stolidly on. When they found a rock face where they could shelter, they slept, as the summer sun scraped its way around the horizon, and the sky faded again to its deepest midnight blue.

Once, Silverhair woke to find herself staring at a snowy owl, a mother perched on her nest with her brood of peeping chicks.

The mother was a white bundle of feathers, standing out clearly against gray shale. Her mate coursed over the rough vegetation, searching for lemmings to bring to his nest. The owl chicks had been born at intervals of three or four days, and the oldest chick was substantially bigger than the smallest. Silverhair knew that if some disaster occurred and the owls’ food supply was threatened, the largest owlet would eat its smallest sibling — and then the next smallest — then the next.

It was brutal. But it was the owls’ way of assuring that at least one youngster would survive the harshest times. The little tableau of beauty and cruelty seemed to summarize the world, this cruel summer, to Silverhair.

The mother owl beat her broad wings slowly, and stared at Silverhair with great sulfur-yellow eyes.

As the endless day wore toward its golden noon, they drew nearer the place where Lop-ear had fallen.

They reached the low ridge near the south coast. Silverhair remembered this place. It was here she had shared Lop-ear’s warmth — here they had encountered the Lost with his thunder-stick — and here she had last seen the body of Lop-ear, like a squat, fur-coated boulder.

The body was gone.

But there were Lost here.

Eggtusk led the two Cows behind an eroded outcrop of rock. The mammoths huddled together uncertainly. Eggtusk raised his trunk cautiously over the rock; the hair of his trunk streamed behind his head.

The mammoths had not been seen. The Lost didn’t seem very observant; none of them was maintaining a watch for wolves — or mammoths, come to that.

The Lost were sitting in a loose circle on the ground. There were six of them. Three of them carried thunder-sticks, like the one that Skin-of-Ice had used against Lop-ear. And one of them — Silverhair could never forget that smooth, unnatural, hairless head — was Skin-of-Ice himself.

The Lost surrounded the carcass of what looked like a fox. They were drinking a clear fluid from flasks, which they passed from paw to paw. They sat unnaturally upright, with strange sets of loose skin over their bodies, and only a few patches of fur on their scalps and faces.

They were like wolves, she thought. Predators, working at a downed prey. But then, they were not like wolves, for they did not work at the fox’s body with their teeth and claws as wolves will. Rather, they had ice-claws — as she called them, for they were made of something that gleamed like sea ice — ice-claws that they held in their paws, and used to cut into the fox’s passive body.

The Lost were grimy, listless, steeped in misery. They seemed to bicker and snap at each other, sometimes descending into clumsy fights.

All but Skin-of-Ice. He sat apart from the rest, thunder-stick on his lap, watching the others coldly.

Silverhair felt a cold, hard determination gather inside her. All her naive dreams of finding some opportunity to work with the Lost had evaporated with the blows inflicted on Lop-ear. These are my enemy, she thought. I will not live in a world that contains them, and I will oppose them to my dying breath.

But to do that, I must understand them.

"We’re in no danger here," said Eggtusk in a soft rumble, inaudible to the Lost. "I’m sure they can’t see us. According to the Cycle, the Lost have poor hearing and smell, and we’re downwind of them. And besides, three grown mammoths against six — or sixty — of those skinny creatures should be no match."
