Eleven-year-old Gemini has never had a real friend. She's been too busy just trying to survive. She lives in a broken down motel on the wrongest side of any town, sleeps in a locked closet, and endures abuse at the hands of a mother who lives to crush dreams like so many tiny bones. But Gemini can't help but believe something bigger is on its way to rescue her from this nightmare. And one night Gemini finds a crack where two worlds collide, slipping into a parallel universe where she is shocked and delighted to meet her first and only real friend. The alternate version of herself. This uncanny meeting with her mirror image creates a magical connection that heals Gemini's hurts, and sets off a cataclysmic adventure that propels the identical girls through a coming of age tale unlike any other.
