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.

Jasper's voice was like waiting for rain during a drought. You got excited when the clouds went grey, hoping the sky would open and quench your thirst. Even a cool breeze felt like a tease. Every time Jasper opened his mouth it was the same one single drop from a leaking faucet. Yet it was never enough. He was mine. My dear deaf boy. I know you see me. I know you can see me call for your attention. I know you can feel my heart pound and my hands shake when I come near. You don't have to be able to hear to understand these three words. I love you. Do you hear me now?

"I'm pregnant." and "I never cared." are two deadly sentences that Aerial Mason never wants anyone to say to her. So how ironic is it when those exact words are said by her best friend and the one she loves the most?
