Together, they find themselves drawn to the tight-knit community of Mill Grove, Pennsylvania. It’s as far off the beaten track as they can get. At first, it seems like the perfect place to finally settle down. Then Christopher vanishes. For six awful days, no one can find him. Until Christopher emerges from the woods at the edge of town, unharmed but not unchanged. Soon Kate and Christopher find themselves in the fight of their lives, caught in the middle of a war playing out between good and evil, with their small town as the battleground.
