At least, that's what she believes. Her last day on Earth, she ruined the life of the person she loves most - her little sister, Emmy. So when Bea awakens from a fatal car accident to find herself on an airplane headed who knows where, she's confused, to say the least.

Once on the ground, Bea receives some truly harrowing news: she's in purgatory. If she ever wants to catch a flight to heaven, she'll have to help five thousand souls figure out what's keeping them from moving on.

But one of Bea's first assignments is Caleb, the boy who caused her accident, and the last person Bea would ever want to send to the pearly gates. And as much as Bea would love to see Caleb suffer for dooming her to a seemingly endless future of eating bad airport food and listening to other people's problems, she can't help but notice that he's kind of cute, and sort of sweet, and that maybe, despite her best efforts, she's totally falling for him.
