Absolutely stellar! This horror novel had definite "Haunting of Hill House" vibes. I couldn't put it down. It was compulsively readable, creepy, and super intriguing! When Maggie was 5 she and her parents lived in a huge hulking house that turned out to be haunted. They fled after 20 days never to return. Her father wrote a bestselling book about their experience and that book has changed Maggie's life. She was too young to remember those 20 days so all she knows is what her father wrote about it and she doesn't believe any of it. Her parents refused to ever discuss it with her. When her father dies she discovers that she has inherited the house. She didn't even know her father still had it. What else was he lying to her about. She goes to the house to flip it and try to sell it for a profit, but really she's going for answers. Chapters alternate between Maggie's present day experiences in the house and excerpts from her fathers book. So good and I didn't see the ending coming. I loved it! Riley Sager hits another one out of the ballpark!
