This book certainly kept me entertained, and had some genuinely spooky moments. However, this book was not for me. I gave it 2 stars.

One thing that didn't work for me was the relationship between the main character and her boyfriend. He was super nice and tried to help provide for her, but she's very independent and would refuse most of the stuff he got her.
They would fight, and then make up. That's how 90% of the relationship went throughout the book.

I also facepalmed a lot over the denial of ghosts. While I understand Mara's reasoning for not believing in the supernatural, it became hard to believe she could deny the house being haunted. Especially when supernatural things would happen right in front of her, she'd freak out and try to leave the house, and then decide to stay anyway.
I did love the concept of an old serial killer House being super haunted, and loved some of the scares in the book.
Some moments were super tense!

I also loved the mixture of humor and horror. I like a good laugh to help recover from a bone-chilling spook.
