Roxy is like every other high school senior––she loves her friends, her car, and hanging on the sidelines of her boyfriend's football games. She lives a picturesque life. But every night her world gets turned upside down––Roxy dreams of a fantastic past she can't remember ever living.

In her dreams, Roxy is a warrior, incredible on the battlefield. But the dreams usually end the same way––a mysterious man not only finds her but kills her, and she wakes up screaming. Who is this man that stalks her nightmares? It isn't until Adam, a mysterious, handsome newcomer at Titan Valley High, barges into her life that Roxy starts putting together the clues of her past life, and the demons she must still face down.
