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.

Two kids growing up in Inner City Dublin, one of them the class clown with an incredible gift for music, the other one a straight A student with her mind set on the stages of Broadway. They say opposites attract and this seems to be the case in summer when the days are long and hazy and everything seems okay. Then he drops the bombshell and she's left all alone without her best friend to deal with one of the most difficult thing a teenager will ever face. He's away, chasing his dream with girls falling at his feet, he doesn't have time for his normal Irish girl anymore and she has to let him go. She's at home, forced to let her dream slip away and she blames him, it isn't fair. Their lives follow parallel to eachother, on opposite sides of the Atlantic, taking similar twists and turns. Until one strange twist of fate and they're thrown back together in the most unusual way. But can they let go of the past enough to get on with the future? Is their too much bad blood? And they say true love never dies, but it isn't that easy, especially when your best mate is involved...
