two unstable runaways meet on the rooftop of their apartment building on new year's eve, ultimately falling in love overnight.

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.

"Three days, Ethan." She whispered. "Three days until I'm supposed to meet the one I'm supposed to be with." "We can make it work." I cry. "That's not how it goes."
