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.

Cherry blossom lipstick: check Smokey eyes: check Skinny jeans: check Dead kid in the mirror: check For sixteen year old Mattie Hathaway, this is her normal everyday routine. She's been able to see ghosts since her mother tried to murder her when she was five years old. No way does she want anyone to know she can talk to spooks. Being a foster kid is hard enough without being labeled a freak too. Normally, she just ignores the ghosts and they go away. There's a little glitch this time. The ghost she sees is her foster sister, Sally. Everyone thinks she's just another runaway. Mattie knows the truth, though-she's dead, murdered. Foster kids look out for each other and Mattie feels like she has to help Sally, but she can't do it alone. Against her better judgment, she teams up with a young police officer and together they set out to discover the truth of Sally's disappearance. Now the killer has set his sights on her. It becomes a race to see if she can find the truth before the serial killer finds her.
