Military historian Luke Alcott leaps at the chance to live in the seventeenth-century country mansion of Eelmoor Hall, home of the Royal Military School of Medicine, after being offered a job cataloging the school's archives. Luke believes he chose the perfect place to start a new life and put his broken past behind him. But soon after settling into the old house, he hears strange noises--like footsteps--and he begins to suffer from terrible nightmares. The only person Luke can turn to for help is the taciturn caretaker, Jay, a veteran of the Afghanistan war who carries an old battle wound. Together they try to understand Eelmoor Hall's history and decipher what could be causing the haunting. As the weather grows colder and snow dusts the countryside, a child goes missing. Luke needs to deal with his own demons and learn to trust in love again if he hopes to face down the angry spirit and find the missing girl.
