Something is wrong with Elena Vale. It starts with a whisper in her mind telling her to pick up a knife, to follow a man.

She tries to resist, but the commands overwhelm her, and when she wakes up after a blackout, there's blood on her hands and no memory of what she's done.

Haunted by fragmented memories and pursued by the very people who programmed her, Elena discovers she's part of a secret black-ops experiment designed to create a mind-controlled assassin.

The more she uncovers, the clearer it becomes: She was never meant to survive this.

Now, Elena must fight for control of her own mind, unravel the conspiracy, and stop the next target-before the voice inside makes her kill again.
