A disturbing but intriguing premise leads to a fast paced & well written romantic suspense novel. Cain is a consulting detective who literally immerses himself in crime scenes in order to gain insight into the mind of the killer. Mercy is the only survivor of his murderous father's last killing spree. When he breaks her out of the mental health facility where she was being held, they find that they have more in common than murder.
