At eighteen, she’s a top notch secret agent, and her life is going exactly the way she wants. She goes by different names—Mariah, Amelia—and, using makeup and wigs, changes her appearance at will. Now, she works as a double agent, living a life of lies and even going so far as to blame innocent people for her infractions to avoid detection. Somone out there knows her real name, though. She was born Rebecca; she was also born a twin. She hasn’t seen her sister, Sarah, for a while, so Rebecca is understandably surprised when Sarah calls asking to see her. They slowly rekindle their relationship, Rebecca always maintaining her carefully protected cover. Soon, though, she wonders if Sarah might be up to something.

With Sarah’s arrival, Rebecca’s discreet, orderly life changes. Everything starts going wrong. As Rebecca struggles to keep up her false identities, she begins to question her actions. Should she continue to ignore her morals in the name of excitement, or is it time to fight for what she knows is right? Changing her lifestyle means destroying the evil she has unwittingly created and earning the trust of the people who really matter, but she might be too late as past indiscretions come back to haunt her.
