Bridging the gap between the living and the dead, there are so many departed adults she can barely handle her ability. With winter approaching, Everly can't fight the dead any longer. She has to listen to the ghosts in order to understand what caused the Event and help keep the children alive. What she doesn't realise is that her association with the spirits runs far closer to home than she could ever imagine.
