" He wonders, without necessarily believing in ghosts, whether their ghosts wander. It comes to him that even if they do, even if he were to take up his coat now and go walking the back roads and the mountain sides, he wouldn't meet them. Their lives and their deaths grew out of a land that Cal isn't made from and hasn't sown or harvested, and they've soaked back into that land. He could walk right through those ghosts and never feel their urgent prickle. He wonders if Trey ever meets them, on long walks homewards under the dimming sky. "
