Mercy (Hardcover)

He taught me to kill. Murder is in my blood now. It runs through my veins and though I hide the monster I see in the mirror with ink, it doesn't keep him from coming out. My street name is Mercy, but I never show any. Except for her. I watch Becca, though she doesn't know. She saved me a long time ago; the day my father killed my mother. Her bravery turned her into a target. My father holds a grudge and knife with the same proficiency, and Becca is the focus of his hatred. And I'm the only monster who can save her.
