It’s September 1, 1894, and 13-year-old Maggie Grant and her family are about to face a terror like none they’ve ever experienced. Having recently moved to the newly constructed town of Hinckley, Minnesota, they are caught in the path of one of the deadliest forest fires in history. Separated from her brothers and forced to flee, Maggie begins a harrowing train ride to Duluth, Minnesota, as the fire rages around her. Once there, Maggie must make a choice–should she stay in Duluth, or can she face her fears and return to what remains of Hinckley to search for her brothers?
