Urges (The Urges #1)
Sky Corgan

Trent Stevens is both the man of Fennel's dreams and her nightmares. He swooped in to rescue her from herself and then disappeared without a trace, leaving Fennel confused and mentally scarred. When he resurfaces to save the day again, she can't figure out if he's good or bad. All she knows is that there's a darkness about him that intrigues her.
