But when Kieran Varys, disappears in a haze of blood, the only person left looking for him is Kieran's terrifying, obsessive architect: a man named Ben. Now Riley must navigate a landscape of motorway services, posh houses, and monstrous authority, and figure out if he's bait, a witness, or something more terrifying—a student.
