Seventeen-year-old Reed had never believed in the concept of destiny and love, so when her best friend dragged her in a search for their "soulmates" one Saturday night, Reed knew it wasn't going to end well. She couldn't have been more right, seeing as: a.) Her best friend, convinced she had found her soulmate, disappeared with some random guy. b.) Said best friend had Reed's purse and the car keys, leaving her no choice but to accept said random guy's friend's offer to look for their missing companions together. c.) Said random guy's friend was annoying, arrogant, and recklessly impulsive. d.) Oh, and he was hot, too.

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.
