A single mother working in the gothic mansion of a reclusive horror director stumbles upon terrifying secrets in the captivating new novel from the national bestselling author of Good Girls Don't Die and Horseman.

Harry Adams has always loved horror movies, so it's not a total coincidence that she took the job cleaning house for movie director Javier Castillo. His forbidding graystone Chicago mansion, Bright Horses, is filled from top to bottom with terrifying props and costumes, as well as glittering awards from his career making films that thrilled audiences—until family tragedy and scandal forced him to vanish from the industry.

Javier values discretion, and Harry has always tried to clean the house immaculately, keep her head down, and keep her job safe—she needs the money to support her son. But then she starts hearing noises from behind a locked door. Noises that sound remarkably like a human voice calling for help, even though Javier lives alone and never has visitors. Harry knows that not asking questions is a vital part of working for Javier, but she soon finds that the sinister house may be home to secrets she can't ignore.
