The sun stood just one hand above the horizon now, descending quickly into the wavy line where the foothills declined to the valley floor. Even in high summer the days seemed to end this way, in a kind of plunge. Peter cupped his eyes against the glare. Somewhere out there-past the fireline, with its loose jumble of felled timber, and the grazing grounds of Upper Field and the dump with its pit and piles, and the scrubby woodlands hills beyond-lay the ruins of Los Angeles and, farther still, the unimaginable sea. When Peter was a Little and still living in the Sanctuary, he had learned about this, in the library. Although it had been decided, long ago, that most of the books the Builders had left behind were of no value, and potentially confusing to the Littles, who were not to know anything about the virals or what had happened to the world of the Time Before, a few were allowed to remain. Sometimes Teacher would read to them, stories about children and fairies and talking animals who lived in a forest behind the doors of a closet, or else allow them to select a book on their own, to look at the pictures and read as best they could. The Oceans Around Us: that had been Peter’s favorite, the book he’d always chosen. A faded volume, its pages dank-smelling and cool to the touch, the cracked binding held together by bits of curling yellow tape. On the cover was the name of the author, Ed Time-Life, and inside, page after wondrous page of pictures and photos and maps. One map was called the World, which was everything, and most of the World was water. Peter asked Teacher to help him read the names: Atlantic, Pacific, Indian, Arctic. Hour after hour he sat on his mat in the Big Room, the book cradled in his lap, turning the pages, his eyes locked onto these blue spaces on the maps. The World, he gathered, was round, a great watery ball-a dewdrop hurtling through the sky-and all the water was connected. The rains of spring and snows of winter, the water that poured from the pumps, even the clouds above their heads-that was all part of the oceans, too. Where was the ocean? Peter asked Teacher one day. Could he see it? But Teacher only laughed, as she always did when he asked too many questions, dismissing his concerns with a shake of her head. Maybe there’s an ocean and maybe there isn’t. It’s only a book, Little Peter. Don’t you go worrying about oceans and such.

But Peter’s father had seen the ocean: his father, the great Demetrius Jaxon, Head of the Household, and Peter’s uncle Willem, First Captain of the Watch. Together they’d led the Long Rides farther than anyone had ever gone, since before the Day. Eastward, toward the morning sun, and west to the horizon line and farther still, into the empty cities of the Time Before. Always his father returned with stories of the great and terrible sights he’d seen, but none was more wondrous than the ocean, in a place he called the Long Beach. Imagine, Peter’s father told the two of them-for Theo was there as well, the two Jaxon brothers sitting at the kitchen table of their small house in the hour of their father’s return, raptly listening, drinking his words like water-imagine a place where the ground simply stopped, and beyond that place an endless tumbling blueness, like the sky turned upside down. And sunk down in it, the rusting ribs of great ships, a thousand thousand of them, like a whole drowned city of man’s creation, jutting from the ocean’s waters as far as the eye could see. Their father was not a man of words; he communicated only with the most sparing phrases and parceled his affections the same way, letting a hand on a shoulder or a well-timed frown or, in moments of approval, a terse nod from the chin do most of his speaking for him. But the stories of the Long Rides brought out the voice in him. Standing on the ocean’s edge, his father said, you could feel the bigness of the world itself, how quiet and empty it was, how alone, with no man or woman to look at it or say its name through all the years and years.

Peter was fourteen when his father returned from the sea. Like all the Jaxon males, including his older brother, Theo, Peter had apprenticed to the Watch, hoping someday to join his father and uncle on the Long Rides. But this never happened. The following summer, the scouting party was ambushed in a place his father called Milagro, deep in the eastern deserts. Three souls lost, including Uncle Willem, and there were no more Long Rides after that. People said that it was his father’s fault, that he had gone too far, taken too many chances, and for what? None of the other Colonies had been heard from in years; the last, Taos Colony, had fallen almost eighty years ago. Their final transmission, back before the Separation of the Trades and the One Law, when radio was still permitted, said their power plant was failing, the lights were going out. Surely they’d been overrun like all the others. What was Demo Jaxon hoping to accomplish, leaving the safety of the lights for months at a time? What did he hope to find, out there in the dark? There were those who still spoke of the Day of Return, when the Army would come back to find them, but never in all his travels had Demo Jaxon found the Army; the Army was no more. So many men dead now, to learn what they already knew.

And it was true that from the day Peter’s father returned from the last Long Ride, there was something different about him. A great weary sadness, as if he’d leapt abruptly forward in age. It was as if a part of him had been left in the desert with Willem, whom Peter knew his father loved most of all, more than Peter or Theo or even their mother. His father stepped down from the Household, passing his seat to Theo; he began to ride alone, leaving with the herds at first light, returning just minutes before Second Evening Bell. He never told anyone where he went, as far as Peter knew. When he asked his mother, all she could say was that his father was in his own time now. When he was ready, he would return to them.

The morning of his father’s final ride, Peter-a runner of the Watch by this time-was standing on the catwalk near Main Gate when he saw his father preparing to leave. The lights had just gone down; Morning Bell was about to sound. It had been a quiet night, without sign, and for an hour before dawn, a light snow had fallen. The day broke slowly, gray and cold. As the herd was gathering at the gate, Peter’s father appeared on his mount, the great roan mare he always rode, headed down the trace. The horse was called Diamond because of the marking on her brow, an orphaned splash of white beneath the swishing mask of her long forelock; not an especially fast mount, his father always said, but loyal and tireless, and quick when you needed her to be quick. Now, watching his father holding her reins, standing at the rear of the herd while he waited for the gate to open, Peter saw Diamond do a little quickstep, tamping down the snow. Jets of steam puffed from her nostrils, swirling like a wreath of smoke around her long, self-possessing face. His father bent low and stroked the side of her neck; Peter saw his lips moving as he whispered something, some gentle encouragement, into her ear.

When Peter thought of that morning, five years ago, he still wondered if his father had known he was there, observing him from the snow-slickened catwalk. But he had never lifted his eyes to find him, nor had Peter done anything to alert his father to his presence. Watching him as he spoke to Diamond, stroking the side of her neck with his calming hand, Peter had thought of his mother’s words, and knew them to be true. His father was in his own time now. Always, in the last moments before Morning Bell, Demo Jaxon would retrieve his compass from his waist pouch and open it once to examine it, then snap it closed as he called his head count to the Watch: “One out!” he would call, in his deep, barrel-chested voice. “One back!” the gatekeeper would reply. Always the same ritual, meticulously observed. But not that morning. It was only after the gates had opened and his father had passed, taking Diamond down the power station road, away from the grazing fields, that Peter realized his father had carried no bow, that the sheath at his belt was empty.
