Night Before 
Savannah series, book 1

In the dark shadows of Savannah, a serial killer strikes. It’s an act of sinister precision that has happened many times before — every victim an offering to a hunger that can never be sated. Catilyn Montgomery Bandeaux wakes, covered in blood. But Caitlyn has no memory of the night before, when her estranged husband was brutally murdered like so many others she has known . . . Dodging the police and haunted by horrifying, fragmented memories, Caitlyn turns to Adam Hunt, the city’s new psychologist. But how far can she really trust him? For as a twisted killer strikes again and again, Caitlyn is about to discover that those who appear the most innocent can be the most evil.
