I was most definitely tense while reading this book. The suspense and horror aspects was executed well. But it's Tananarive Due, there is not a book by this author that I did not enjoy. This is a story about a man who is trying to figure out why he was not getting enough sleep. His lack asleep is affecting his job, his marriage, and the livelihood of his children. At some point him and his wife seeks therapy and things take an interesting turn. This book has a several themes that includes mental health and family secrets. I enjoy both themes throughout the book. There is a Content Warning of white folks saying and doing racist things. Tananarive has a gift for writing strong characters and I am never annoyed with being in the mind of her MCs.
