I was really interested in it at first and then when the plot twist revealed itself it did not make sense.
Spoiler alert!!!
A lot of her inner dialogue contradicted that she had been in the house many times or that she had a "feeling" something bad happened in the house when she was the one who committed a murder there.
My biggest struggle with the book was how did the husband not know that she was the main character in the book of the Phyiciatris. Knowing her family and friends he obviously new her fiance and 2 friends had been murdered in a cabin the woods but never new there was a New York times best seller written about his wifes experience?
