There is a monster on the loose, a serial killer murdering young women near Oklahoma City. On each corpse he writes his name in blood: THE TIN MAN
But while the villain claims to be heartless, he's not beyond making a mistake. This time he left his prey alive, and ex -- homicide detective Nick Lassiter plans to use her to crack the case wide open. Yet, Ravyn Skyler is nothing like he expects. She remembers little of the crime, and for a victim she has a deep reserve of quiet strength. In her eyes he sees both helpless waif and merciless vigilante, in her kiss he tastes both passion and power. With a tale of a tin man, it only seems fair that there's a witch. And this witch guards a secret that threatens not only their lives, but their souls.
