Shelby is nervous to start her senior year after spending the whole summer away from home. After all, it's hard to be carefree when you're trying to protect a secret.

The treatment erased Shelby's memory of the accident, but she can't help feeling as if a piece of herself is missing, that the treatment took more than the doctors claimed.

So when Shelby starts hallucinating a boy with dark and mysterious eyes, she knows it must be a side-effect of the clinical program. Except you can't kiss hallucinations. And this boy insists that they know each other and are in love...
