After her most recent disaster with the King of the Unrepentant Jerks, Isabel "Izzy" Palmer is finally convinced that the only male she truly needs in her life is Henry, her lovable part wolfhound, part who-knows-what. Henry's faithful, he adores her madly, and he's great fun to sleep with. So who needs the additional heartache?

But even armed with powerful knowledge and a new resolve, Izzy starts to feel that familiar itch ... and it's all because of Nick. He's a vet for goodness sake — confident, handsome and compassionate — if a bit rough around the edges. After teasing her about Henry's unusual looks and questioning her most recent choice in men, Nick then has the gall to turn halfway charming. But he doesn't stop at halfway, and though she already has a best friend, Izzy realizes it doesn't preclude her from having a perfect match, too.
