In 2011 Claire is leaving London and a broken relationship as she makes a new life for herself at Ellis Chase, a grand estate that was once the Ellingham Lunatic Asylum. From the moment she moves to her new home, strange things begin happening, and she is haunted by terrifying dreams and visions. Claire fears she is losing her sanity.
In 1887 Evie was trapped in an unhappy marriage awaiting the birth of her first child. She had a chance at happiness, but her brutal husband would stop at nothing to block it—even if that meant committing her to Ellingham Lunatic Asylum for a crime she did not commit.
The fates of the two women become increasingly entwined. Evie cannot rest until she has saved Claire and proven her own innocence. Can Evie save her, or is Claire doomed to repeat Evie's tragic history?
