The only thing stronger than a witch's promise is a mother's vengeance...
Sarah loved and trusted no one in her close-knit coven more than her oldest friend, Abigail. Then Abigail's son was found dead at a house party and Sarah's daughter, Harper, was accused of murdering him. While the entire village of Sanctuary was consumed by the witch hunt, Sarah and Harper lost everything but their lives.
They fled to the storm-wracked coastal reserve of Bittershore for refuge, but now the past is catching up with them and the secrets they have kept not only from each other, but from the entire world, are set to be unleashed at last...
