Seeing good and evil spirits is a gift Zoe guards with her life. Despite her guardian angel's disappearance, Zoe forces herself to accept that she still has a purpose-- but how does she carry the weight of her brother's drug abuse, the hardship of living with an autistic sister, and a best friend who's obsessed with a guy who only wants Zoe? She never felt more alone. When a mysterious spirit appears, Zoe thinks she has a new guardian angel. Instead her brother's addiction worsens, her parents are on the brink of separation, and her best friend tries to kill her. The spirit she thinks is her new guardian isn't there to protect her: he's out to destroy her family and seize Zoe's soul...for Hell.
