There are three things that Dr. Briony Theale loves. Her job as a veterinarian, a good bar of rich, dark chocolate, and Rico, the ranger in charge of the Wildlife Rescue center. When a casual dinner with Rico turns surprisingly intimate, Briony realizes that she might just have a chance with him after all, if only she could lose a few pounds. It's the ultimate sacrifice, but Briony goes cold turkey, and swears off chocolate forever.

Rico Montgomery fell hard for Briony the first time he set eyes on the curvy little doctor. Her rich brown hair and cocoa skin trigger cravings he can barely control, and her fragrance is like the sweetest, richest chocolate he's ever scented in his life. That's a bad thing for Rico, because to a werewolf like him, chocolate is literally a toxin. After his pack warns him off the very human doctor, Rico finds himself even more drawn to Briony.

Rico can't live with it, and Briony can't live without it. And when a certain wandering wolf finds a bag of chocolate in the trash near Briony's clinic, these two will find out just how toxic love can be.
