My name is Verity Guerra. I'm on the run from the most ruthless mafia Don in New York-my father. For the past few months, my sister and I have been in Witness Protection, and I'm determined to live long enough to testify against him. I knew he'd send someone after me. But I didn't bank on a hit man known only as X, with cheekbones sharp enough to grate Italian cheese, and muscles that won't quit. But what he doesn't know just may kill him. Behind my pretty façade, I'm a cold-blooded killer. Too bad X is determined to end me, or I might just fall for those piercing blue eyes.Call me X. I'm a contract killer, hired to make sure Verity Guerra turns up dead. A beautiful face won't stop me from doing my job. Killing isn't just my work-it's in my blood. But her dark eyes, silky hair, and tattoos mask a lethal killer. Finally, someone worthy to be called my mark. When her little sister goes missing, we have only one question-do we stop trying to kill each other long enough to get her back? Turns out love and hate aren't so far apart. Can we fight our desire for each other ... or will we both end up dead?
