Behind him, forming a comforting cloud of noise and smells and activity, lay the Colony itself, its houses and stables and fields and greenhouses and glens. This was the place where Peter had lived his whole life. Even now, facing away to watch the herd come home, he could hold each meter of it in his mind, a mental inventory in three dimensions with complete sensory accompaniment: the Long Path from the gate to Old Town, past the Armory with its music of hammering metal and the shaded recesses of West Glade, where Auntie lived; the fields with their rows of corn and beans, the backs of the workers bent low over the black earth, tilling and hoeing; the broad, semicircular plaza known as the Sunspot, where the trading days and open meetings of the Household were held; the Sanctuary, with its ringing bell-tower and bricked-in windows and coils of concertina wire, barricades that somehow failed to suppress the voices of the Littles playing in the courtyard; the pens and barns and grazing fields and coops, alive with the sound and smell of animals; the three greenhouses, their interiors obscured by a fog of humidity, and, standing adjacent, the vast scavenged bounty of the Storehouse, where Walter Fisher presided over the stalls of clothes and tools and food and fuel; the blocks of houses in various states of repair, from crumbing cabins long abandoned to those that, like Peter’s, had been continuously occupied since The Day; the orchard and buzzing apiary and old trailer park, where nobody lived anymore, and, beyond it, past the last houses of the North Quarter and the Big Shed, at the base of the cutout between the north and east walls in a zone of perpetual cooling shade, the battery stack, three gray bulks of humming metal wrapped by wire and pipe, still resting on the sunken wheels of the semi-trailers that had pulled them up the mountain in the Time Before.

The herd had crested the rise; Peter watched from above as they approached, a jostling, bleating mass that flowed like liquid up the hill, followed by the riders, six in all, tall on their mounts. The herd moved as one toward him through the gap in the fireline, their hooves kicking up a cloud of dust. As the riders passed under his post, each gave Peter a tight nod of acknowledgment, as they had for each of the last six evenings.

No words would pass between them. It was bad luck, Peter knew, to speak to someone waiting on the Mercy.
