Beatrice Bird is haunted by ghosts --- a gift she's had since she was a small child. Unfortunately, it's an ability that has now grown more intense, shifting from flashes and feelings to physical manifestations she can't escape. In a desperate attempt to find relief, Beatrice flees her home, her partner and her psychology practice in San Francisco for a remote island with only nuns and a few cows for company. She doesn’t call home. She sees as few people as she possibly can. Then she meets Anne Iredale, a timid woman who has lost everything that matters to her. For the first time in a long time, Beatrice's gift will be called on to help someone in need. But the ghosts have taken on an even darker edge --- and there is something sinister lurking in the shadows.

Brittany, 1762. There hasn’t been a witch born in the Orchière clan for generations. Ursule Orchière has been raised on stories of the great witches of the past. But the only magic she knows is the false spells her mother weaves over the gullible women who visit their fortune-telling caravan. Everything changes when Ursule comes of age and a spark of power flares to life. Thrilled to be chosen, she has no idea how magic will twist and shape her future. Guided by an ancient grimoire and the whispers of her ancestors, Ursule is destined to walk the same path as the great witches of old. But first, the Orchière magical lineage must survive. And danger hovers over her, whether it’s the bloodlust of the mob or the flames of the pyre.

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.

Brittany, 1821. After Grand-mère Ursule gives her life to save her family, their magic seems to die with her. Even so, they 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, but new generations struggle not only to master their power, but also to keep it hidden. But as time races onward and World War II looms on the horizon, magic is needed more than ever --- to change the entire course of history.
