Reeling from her fiancé’s infidelity and her mother’s deteriorating condition, Stella begs her best friend, Dan, to take her somewhere as bleak as she feels. They end up exploring the ruins of an abandoned 19th-century asylum. Days later, Stella wakes there again—this time as a patient more than eighty years in the past. The crumbling halls have been restored, the wards are full, and their inhabitants bear uncanny resemblances to people Stella loves in the present. As she struggles to determine whether she’s traveled through time or lost her mind, Stella is drawn into the asylum’s darkest secrets—and toward a magnetic doctor who could save or shatter her. As the line between obsession and salvation blurs, Stella’s grip on reality begins to slip. If she can’t uncover what brought her there, she risks becoming a permanent resident—or forgetting she ever wanted to leave.
