Blood Bound

Fueled by grief after his fiancée is brutally murdered, Detective Sam Walker focuses on finding her killer, a calculating predator who binds books with human skin. Falling in love again is not on his radar.
Dani Barrington, the newest member of the Victim and Witness Assistance Unit and a survivor of her own terrifying attack, helps him discover the link between the monster's known victims. She's not looking for love, either. All she wants is peace.

Despite his hardened heart, Sam is struck by Dani's strength and determination, especially when her inquisitive nature makes her the killer's next target. He must find a way to protect her or risk losing the one woman who can bring his dead heart back to life.
