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.

Oh my god. This is not happening, not to me, not now. Shit. I should have never wished for anything. I should have been careful. I look at myself in the mirror. Everything about me seems normal, except for a pair of white wings behind my back. They fell perfectly behind me as if they were there my whole life. But no they just appeared this morning when I woke up with unbearable pain.  Have you ever wanted to run away? Have you ever wanted to change your life? Ever wanted that one wish to make it all okay? Think again. Wishes are nice and all but making a deal with the devil is another thing. What will Sarah do when she accidentally makes the deal with the devil? Will she realize the meaning of "Be careful of what you wish for"? Or will she fall for the devil?
