While she battles her own demons during the day, Indigo's nights are haunted by something much darker. Everyone else may be enjoying the summer, but Indigo's life isn't going so well. Her dad's marriage just ended in a very public divorce, and now he's drinking again. Indy barely graduated from high school, she just lost her job, and she doesn't know what to do with her life. The stress is causing her nightmarish sleep paralysis--or so she thinks. Indy confides in her best friend, Kasia, who blames "The Mare" for her troubles--the spirit of someone wronged that saps its victim's energy at night. It sounds crazy to Indy, but is it? Steeped in the nostalgia of lazy summers and mixtapes, concert tickets and coffee, The Mare is a story about friends, family, and finding one's way--with a touch of the supernatural and a powerful, surprising twist.
