Nocturnal Origins - Nocturnal Lives, #1

Some things can never be forgotten, no matter how hard you try. Detective Sergeant Mackenzie Santos knows that bitter lesson all too well. The day she died changed her life and her perception of the world forever. It doesn't matter that everyone, even her doctors, believe a miracle occurred when she awoke in the hospital morgue. Mac knows better. It hadn't been a miracle, at least not a holy one. As far as she's concerned, that's the day the dogs of Hell came for her. Investigating one of the most horrendous murders in recent Dallas history, Mac also has to break in a new partner and deal with nosy reporters who follow her every move and who publish confidential details of the investigation without a qualm. Complicating matters even more, Mac learns the truth about her family and herself, a truth that forces her to deal with the monster within, as well as those on the outside.
But none of this matters as much as discovering the identity of the murderer before he can kill again.
