In Arkham, Massachusetts, the line between the haves and the have-nots is steeped in colonial tradition that stretches back over four hundred years. The Daughters of Arkham, a secret society of wealthy women, stand at the center of it all. On the surface, their power is assured by blood and money. Beneath it, they hold pacts with strange entities beyond the understanding of mortals. Fourteen-year-old Abigail Thorndike is the scion of the most important family in Arkham. When she becomes mysteriously pregnant, she is outcast, left alone to unravel the secrets of her haunted town. Abby must risk her status, her humanity, and the fate of her unborn child to stand against her family and the rising darkness to defend the very town that shunned her.
