Chelsea is a fairly regular teenage girl. She lives with her mom and her twin brother, Heath. Their lives went on in routines, anything new meant a change of dinner plans for that night. When a boy moves in next door, how will she react when he decides to make friends with her? And when she finds out her dad, previously in an asylum, comes back to move in with them, how will she manage to maintain her ordinary lifestyle? Will she even try?

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.
