Sullen Andrews is a senior in college and a member of the Crescent Moon pack. One day, her mother calls with good news: she's met a new man after her husband—her true mate—died. Sullen goes home to meet her mother's new boyfriend, where she finds out that he's part of a rival pack. Even worse, Sullen is hit with a powerful smell when she gets to the pack lands—her own fated mate. With a boyfriend back at college, Sullen runs in panic, only to find out that fated mate is not only her soon-to-be stepbrother, Roan... but he's also the pack's alpha. And he isn't taking no for an answer.
