Claire de Lune by Christine Johnson

Claire is having the perfect sixteenth birthday. Her pool party is a big success, and her crush keeps chatting and flirting with her as if she’s the only girl there. But that night, she discovers something that takes away all sense of normalcy: She’s a werewolf.

As Claire is initiated into the pack of female werewolves, she finds her lupine loyalty at odds with her human heart. Burdened with a dark secret and pushing the boundaries of forbidden love, she will be forced to make a choice that will change her life forever. . . .
