A weapon. A broken life. A humanity lost.
That is all Anastasia knows, that is all that she is. As an eleven-year-old, she witnessed her family's brutal murder and she's been on the run ever since. She's spent her life training and planning for the day when she can take her revenge.
Kallos Enterprises is a well respected corporation, set on improving the genetic structure of an individual. Or so they say. Anastasia knows, first hand, what kind of monsters lurk behind the pretty walls of those skyscrapers. Armed with combat skills and a beyond perfect memory, she heads to Chicago to uncover the answers to questions that plagued her for years.
After arriving in the city, she meets Logan, a boy from her past who changes all the rules. She doesn't remember him, but he remembers her. His position at Kallos Enterprises is useful, his presence is unnerving, and he makes her question everything she knows about herself to be true. If her perfect memory can't remember Logan, what else about her past is wrong?
Time is running out. Anastasia has nowhere to turn, but to trust the one person who's a memory she should have, but doesn't. With a madman threatening their every step, Anastasia and Logan must uncover the truths behind Kallos experiments and hope that the answers they find won't destroy the world forever.
