Untamed Beast — Kate Donovan

Rick Diaz came to the hotel bar with two goals: to escape the tortured reality of his new existence and to find a woman. Over the last nine weeks both his body and personality have changed--he is stronger, more aggressive, and has an animal magnetism no woman could resist. But he's also afraid that once his transformation is complete, he can never have a real relationship again--giving him one more night to enjoy the pleasure of a woman's touch.

Megan O'Neill turns out to be that woman. Rick used to star in her finest fantasies while they attended college together, though nothing could compare to the fierce passion she experiences during her night with Rick. But when Rick leaves the next morning without saying goodbye, Megan thinks she'll never set eyes on him again...

Until Rick returns to tell her that he is a Guardian, destined to save the world from evil--and that Megan is the only woman who can help him...
