In an isolated house where flowers wilt at a touch and time refuses to move in a straight line, a fragile young widow begins a new life, with a much older husband, she can't quite trust - haunted by warnings, watched by something patient, and carrying a secret that isn't only her own. When an impossible death draws a sharp-witted detective into the house's orbit, he finds a place that bends memory, guards an ancient purpose, and refuses to let anyone leave unchanged. What waits beneath is older than the walls, and the answer, when it comes at dawn, will reach further than anyone expects.
