In 1692, Bridget Bishop was hanged as a witch. Two hundred years later, her legacy lives on in the scions of two very different lines: one dedicated to using their powers to heal and help women in need; the other, determined to grasp power for themselves by whatever means necessary. This clash will play out in the fate of Annis, a young woman in Gilded Age New York who finds herself a pawn in the family struggle for supremacy. She'll need to claim her own power to save herself - and resist succumbing to the darkness that threatens to overcome them all.

After Grand-mere Ursule gives her life to save her family, their magic seems to die with her. Even so, the Orchires fight to keep the old ways alive, practicing half-remembered spells and arcane rites in hopes of a revival. And when their youngest daughter comes of age, magic flows anew. The lineage continues, though new generations struggle not only to master their power, but also to keep it hidden. But when World War II looms on the horizon, magic is needed more urgently than ever.

The second is the sudden reappearance of Barrie Anne's long-lost husband - who is not quite the man she thought she married.
