Midnight Moon by Linsey Hall

Werewolves aren’t real….right?

I’ve been on the run ever since my father sold me out to the mob with promises that I could repay his debt. But no one can hide from the mob forever.
When they find me, they give me two options—pay back my father’s debt or sleep with the fishes. My only shot is to rob the most powerful man in the city—the famed Garreth Locke.
I get more than I bargained for–including the knowledge that magic is real, and Garreth is a freaking werewolf. Soon, I’m swept up into an insane world of wealth and magic that I had no idea existed. As the attraction explodes between us, it becomes harder and harder to keep my secret. I have no idea how I’m going to get out of this alive, or with my heart intact.
