She took the job to save her family. Now she has to survive the night.

Leah, a desperate registered nurse on the verge of losing her family home, accepts a high-paying, last-minute assignment that seems too good to be true. The job: provide round-the-clock care for a reclusive, elderly man in a decaying Gothic mansion miles from civilization.

The rules are simple. Stay inside after dusk. Never unlock the cellar. And never, ever miss a dose of the patient’s "medication."

But as the full moon approaches, Leah realizes her patient isn't just sick. His affliction is older, darker, and more violent than any medical chart could explain. The claw marks on the outside of the bedroom doors and the strange, pained howls that echo through the halls are a terrifying secret the old house has kept for generations.

Trapped by her contract and a raging storm, Leah discovers the horrifying truth: the illness is a curse, the patient is a creature of nightmare, and the house isn't a hospital—it's a cage. When the chains break, she becomes the subject of a relentless hunt within the mansion's claustrophobic walls. Can a lone nurse outwit a monster that wears the face of the man she was hired to protect?

Fans of Stephen King's claustrophobic tension, the atmospheric dread of The Haunting of Hill House, and visceral creature features will love this gripping tale of survival horror. Read it with the lights on.
