Sixteen-year-old Eliza O'Neill has always kept a secret from her family and friends, never telling anyone what she is truly capable of. She attributes her actions to luck, being at the right place at the right time. Deep down, she knows the power within is something beyond her control. Her entire body goes on autopilot by an insatiable impulse with a life of its own whenever someone is in peril. It has been there for as long as she can remember, and the older she gets the stronger the pull. All she ever wanted was to be an ordinary girl, but a life of normalcy seems suddenly out of reach.
