Melissa Heeds thinks she is an average, rebellious teenager from Australia. She is arrogant, strong-willed and stuck in a small town with a broken family. As Melissa struggles through the monotony of school and family life, she soon discovers that she is harbouring a secret skill - a power she knows nothing about and cannot control. This power invades her life, causing catastrophic consequences for Mel and everything around her.
A Sentinel is sent to her house - an armed teacher hell-bent on escorting her to a private academy to control this power before it kills her. Desperate to escape, Mel tests the strict boundaries of the school, only to find that government agents are also interested in her power, and more importantly how to rid her of it. She must discover where this ability came from and unleash its true devastating potential before it kills her.
