The Demon Within — Stacey Brutger

As a punishment for failing his duty as an angel, Ruman finds himself encased in stone in the form of a guardian statue. Every few decades he is given a chance to repent. And fails. Until the totally unsuitable Caly Sawyer accidentally brings him back to life. Nothing is going to prevent him from gaining his freedom, especially some willfully stubborn human determined to kill him.

Caly doesn't trust the mysterious stranger who came out of nowhere and risked his life for hers. As a demon hunter, she knows there is something not quite human about the sexy bastard. Her ability to detect demons is infallible. She should know. She used to be one.

War is brewing between demons and humans. The demon infection that Caly had always considered a curse might just be the key to their survival...if Ruman can keep her alive long enough. Despite the volatile attraction between her and her sexy protector, Caly's determined to do whatever it takes to keep everyone alive. The more Ruman learns about his beautiful charge, the more he questions his duty and loyalty...and dreads the call to return home. If they can't learn to trust each other in time, one of them will die.
