On Midsummer’s Eve, Alinor waits in the church graveyard, hoping to encounter the ghost of her missing husband and thus confirm his death. Until she can, she is neither maiden nor wife nor widow, living in a perilous limbo. Instead she meets James, a young man on the run. She shows him the secret ways across the treacherous marshy landscape of the Tidelands, not knowing she is leading a spy and an enemy into her life.

England is in the grip of a bloody civil war that reaches into the most remote parts of the kingdom. Alinor’s suspicious neighbors are watching each other for any sign that someone might be disloyal to the new parliament, and Alinor’s ambition and determination mark her as a woman who doesn’t follow the rules. They have always whispered about the sinister power of Alinor’s beauty, but the secrets they don’t know about her and James are far more damning. This is the time of witch-mania, and if the villagers discover the truth, they could take matters into their own hands.
