City Wolf - City Wolf Trilogy, #1

Previously published. Book 1 in the series. Zandrea, Nita and Stacy are three girlfriends who are only interested in what club to pop into on Friday and Saturday nights. Zandrea's life is turned upside down when, on break from her shift at the hospital cafeteria, she meets a sexy man with a serious injury in the emergency room. Nita and Stacy refuse to believe the man who Zandrea says disappeared from the hospital is the same guy they meet later at the club.
But who cares. He's hot and he's set his sights on Zandrea. Nothing else matters...until Zandrea finds out what he really is.
