My Girlfriend is a Werewolf by Eve Langlais

Running into a strange white wolf isn’t an everyday occurrence in Derek’s life. Neither is finding a naked—and beautiful—woman alone in the park. Had the wolf been an omen of what was yet to come? Because since meeting Athena, Derek’s life’s been upended.

Chased by thugs and with a ransom on her head, Athena isn’t divulging why she’s a wanted woman. Derek helps her anyway since he’s a gentleman and she keeps his curiosity—and other things—piqued. Besides, he’ll be damned if some greedy doctor is going to kidnap and experiment on innocent people in his own backyard.

But he can’t help but notice Athena’s great sense of smell, or her proclivity for chasing rabbits, or the way she disappears every full moon…
Turns out his Athena’s got a hairy secret.
A howling whopper of one.
Guess he’d better stock up on flea collars and kibble because My Girlfriend is a Werewolf.
