The Lot. Book One. In the Shards of Darkness

Investigator Boris Bisaev of the capital police has been searching for his daughter for a year and a half. Anya disappeared under unclear circumstances. The only clue he has is a playing die made from human bone.

From the author: The police investigation is more like a game of "cat and mouse." Except who is the cat and who is the mouse? A policeman who has lost his daughter versus a criminal obsessed with the game.
