I enjoyed this book while reading it, but I felt that the ending was a bit disappointing. I loved the descriptions, the rich characterizations, and the draw of the mystery. However, some of the storylines felt a bit cursory or unfinished. It's as though we approached the end of the book as the author neared their deadline, so they just gave up. The end is fine, not a cliffhanger, just not nearly as rich as the beginning. My absolute favorite part was the past history of the house...the power and darkness of that part drew me in. The book got lighter and flightier as the story went on.
Also, the heavy overlay of religion got distracting as the book wound down. "I won't get in a theological discussion with a murderer," says the detective, after a three-page theological discussion with a murderer. It's one thing to use religion for characterization and even plot points, its another to push anti-abortion rhetoric in conversation with a serial killer. The author's voice came shouting through from time to time, instead of letting the characters and the story carry the themes.
