Rule #1: Never disobey master's commands. Rule #2: Always strive to please your master. Rule #3: Don't ever kill your master.

Breaking the rules is the ultimate sin.

All I am is a servant. Rules like these keep me alive. They're all I've ever known. Until him. My new master: Marcus Knight, the charismatic and ambitious leader of an underground empire. A man with a history he vows to destroy. With his newfound ownership over me, he seeks to atone for his crimes ... and to satisfy his wicked needs. With love, he shows me what it means to belong to him ... and it makes me question everything. I don't know why he chose me, but it feels too good to be true. And it is. Because I'm going to break all the rules.
