His mom struggles with depression, alcoholism, and a wedge driven between her sister, Janie, and herself. Father Matthew must face the trauma of a past failure that casts a dark shadow on his faith and calling. The hardest is Elise’s demon … a true demonic spirit she made friends with a long time ago.
