His father never returned, which meant he was dead, killed by the virals out in the Darklands, at a place called Milagro. Their father had claimed he’d seen a Walker there, a solitary figure darting in the moonlit shadows, just before the virals attacked. But by that time, with the Household and even Old Chou having turned against the Long Rides, and Peter’s father in disgrace, having resigned to pursue his mysterious, solitary expeditions without the Wall—moving in the expanding orbit that even then had seemed to Peter a rehearsal for something final—no one had believed him. A claim as bold as that: surely it was just Demo Jaxon’s desire to continue the rides that made him claim something so absurd. The last Walker to come in had been the Colonel, almost thirty years ago, and he was an old man now. With his great white beard and wind-bit face, brown and thickened as tanned hide, he seemed nearly as old as Old Chou, or even Auntie herself, Last of the First. A single Walker, after all these years? Impossible.

Even Peter hadn’t known what to believe, until six days ago.

Now, standing on the catwalk in the fading light, Peter found himself wishing his mother were still alive, as he often did, to talk about these things. She’d taken sick just a season after their father’s final ride, the onset of her illness so gradual that Peter had at first failed to notice the raspy cough from deep in her chest, how thin she was becoming. As a nurse, she had probably understood only too well what was happening, how the cancer that took so many had made its lethal home inside her, but had chosen to hide this information from Peter and Theo as long as she could. By the end not much was left of her but a shell of flesh on bone, fighting for a single taste of breath. A good death, everyone agreed, to die at home in bed as Prudence Jaxon had. But Peter had been at her side through the final hours and knew how terrible it had been for her, how much she’d suffered. No, there was no such thing as a good death.
