|| An abandoned building. A dank cellar. And inside it, a cage of bones-with a shocking surprise lurking within. Carver's new thriller will scare the daylights out of you. Into the house. Down the stairs. Through the dripping dark of the cellar. Someone is there. Someone that shouldn't be there. As a building awaits demolition, a horrifying discovery is made inside the basement: a cage made of human bones-with a terrified, feral child lurking within. Unbeknownst to Detective Inspector Phil Brennan and psychologist Marina Esposito, they have disturbed a killer who has been operating undetected for thirty years. A killer who wants that boy back. But the cage of bones is also a box of secrets-secrets linking Brennan to the madman in their midst. With the death toll rising and the city reeling in terror, Brennan and Marina race to expose a predator more soullessly evil than any they've ever faced-and one who is hiding in plain sight.
