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.

Alex Bates has had more than enough of life. Plagued with the agonising guilt of being the cause for his sister's recent death, he's heading down a destructive path. But just as he is about to give into the urge to jump in front of an oncoming train, he's interrupted by a girl. Shy and observant Kalila Woods knows that no words can stop him so she only hands him a packet of Skittles and walks away. And so begins an unlikely friendship. She's on a mission to convince him of the many reasons to live and he's on a journey to find himself along the way. And maybe, just maybe, Alex will realise that dying isn't quite worth it.
