ORKNEY ISLANDS, 1797 – Agnes Tulloch feels a little cheated. This windswept place is not the island paradise her husband promised it to be when they wed. Now with four young children, she struggles to provide for her family while her husband grows increasingly distant.
When a stranger comes ashore to rent an abandoned cottage, Agnes and the other islanders are abuzz with curiosity. Who is this wealthy foreigner and why on earth would he come to Eynhallow? Her curiosity is soon replaced with vexation when her husband hires her out as cook and washerwoman, leaving Agnes with no say in the matter. Agnes begrudgingly befriends this aristocrat-in-exile; a mercurial scientist who toils night and day on some secret pursuit. Despite herself, she’s drawn to his dark, brooding charm. And who is this Byronic stranger sweeping Agnes off her feet? His name is Frankenstein and he’s come to this remote isle to fulfill a monstrous obligation.
Summer 1987: Mark Prewitt’s only priority is to avoid his dad’s new wife and waste time with his friends, but idle nights are the devil’s playground. When his friends decide to pull a cruel prank on the reclusive and strange Farrow sisters, Mark regrets caving in to peer pressure.
Wanting to make amends, Mark is drawn into the mysterious world of the Farrow girls, finding a kindred spirit in the middle sister, George. She is unlike anyone he’s ever known; a practicing witch who uses folk magic to protect her family. They bond over books, loneliness, and homemade spells. She even invites Mark to join a séance to contact her dead sister, who died under mysterious circumstances.
Keeping their relationship secret, Mark learns that living a double life in a town this small is impossible. When the secret is exposed, and his friends plot to punish the witch sisters for stealing one of their own, Mark is forced to choose between these two worlds.
