Abby and her family move into an old home. Abby starts hearing voices through her daughter's monitor, and becomes worried that something in the house is trying to harm her daughter. After doing research into previous owners of the house, she meets a man who was related to the owners, and happens to have a journal that Frances (prior inhabitant) has written. After Abby reads the journal, she becomes even more terrified that something is going to harm Lucy (her daughter), so she stops sleeping. The story digs deeper into both Abby's and Frances' inner demons and their histories.After reading this book, my brain feels muddled. It took a lot of concentration (for me, at least), to keep all of the different stories and characters straight, and to remember how each interacts and relates with the others. I literally feel like I just came out of a whirlwind, and I'm slightly dizzy. I'm wondering if any other readers felt this way?There were some legitimately scary parts in the book. In a couple of places, I literally got goosebumps. It was an interesting story, don't get me wrong, but my brain is just really tired.
