Half angel and half human, Chalice knows that inheriting powers from your parents has its drawbacks. It's the reason she's abducted by a sorcerer, then taken to Chicago, where she's forced to use her supernatural senses to steal cursed objects for her kidnapper. Twelve years later, a note from her dead mother reveals a secret that will change Chalice's life forever.
As much as Chalice would like to tell her magical master to go to hell, it won't do her any good. She's branded with a gargoyle's curse and it takes a lick from the creature's tongue every three days to keep her from changing into the bat-winged devil of her nightmares. The only way to break the curse is to kill the gargoyle. Problem is, gargoyles are supposed to be immortal. Her fallen angel father gives her the secret for killing the beast, but freedom won't come without cost. Everything has its price, and for Chalice, the currency is death.
