Tabby has a peculiar gift: She can communicate with the recently departed. It makes her special, but it also makes her dangerous. As an orphaned child, she fled with her sister, Alice, from their charlatan aunt Bellefonte, who wanted only to exploit Tabby's gift so she could profit from the recent craze for seances. Now a young woman and tragically separated from Alice, Tabby works with her adopted father, Eli, the kind caretaker of a large Boston cemetery.

With the stroke of a pen, twenty-three-year-old Ivy Radcliffe becomes Lady Hayworth, owner of a sprawling estate on the Yorkshire moors. Ivy has never heard of Blackwood Abbey, or of the ancient bloodline from which she’s descended. With nothing to keep her in London since losing her brother in the Great War, she warily makes her way to her new home. The abbey is foreboding, the servants reserved and suspicious. But there is a treasure waiting behind locked doors—a magnificent library.

Once there was a young woman from a well-to-do New England family who never quite fit with the drawing rooms and parlors of her kin.

Soon, whispers of “witch” dogged her footsteps, and Margaret’s power began to wind itself with the tendrils of something darker.

The spirit that inhabits her new home confronts her and charges her with saving her daughter’s life, threatening to take Flora’s if she fails.
