Former soldier, Frankie McGill has returned home from Afghanistan minus half of her left foot and with a plate in her head. After some months in medical care, she's ready to take on the new battle of finding and holding a job. But not just any job. Frankie is a combat-trained paramedic. When all she can find is a position in the small, mostly volunteer fire department of her old hometown, Frankie is immediately plunged into much more than dealing with her own trauma and holding down a job. She moves into a duplex that the previous tenant abruptly abandoned and quickly discovers someone has some dark secrets to hide-and they don't care who they have to kill to keep them hidden. Will Frankie's military training and experience be enough to save her life?
