Ashlyn Calloway is your average teenager. Other than the fact she has powers. I'm talking real, honest to goodness powers. Like a superhero. Only she's not. Ashlyn hasn't shared her secret to anyone in hopes of being normal; but when tragedy strikes in Westlake and troubled secrets buried from the past reappear, will she suit up and play hero or will she collapse under the pressure that rests on her shoulders?

Hadley Jamison doesn't know what to think when she hears that her classmate, Archer Morales, committed suicide. She didn't exactly know him, but that doesn't stop her from feeling like there was something she could have done to help him. So to Hadley's surprise, on the very night of Archer's funeral, she has a run in with Death himself and is offered the chance to go back in time to stop Archer from ending his life. The catch? She only has twenty-seven days to do it. And if Hadley doesn't succeed? Well, she doesn't want to think about that.
