Tessa Young is an 18 year old college student with a simple life, excellent grades, and a sweet boyfriend. She always has things planned out ahead of time, until she meets a rude boy named Hardin, with too many tattoos and piercings who shatters her plans.

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.
