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.

On the outside, Riley Jennings has got it under control. She's the top of the class, ivy-league bound, and plans to go far in life. But nobody knows the dark secret that she lives with; her perfect, football star boyfriend, Blake, is a monster. She's forced to conformity, only to meet the one person who will help her break out of her shell, and break out of her detrimental relationship. Dean Marks, the new rebellious transfer student, has taken it upon himself to help Riley. Little does she know, he's got a dark secret too; one only his protective, controlling, older brother Alex knows about. Together, they will run from their pasts, only to stumble into them once more.
