Hmm I feel like this is written as a young adult book because the POV was solely from a daughter who from 10-23 years old had to care for her mother. The writing, the dialogue was very easy, almost juvenile for an adult horror novel. 

I also went into this blind and really didn’t vibe with the toxic, co-dependent mother-daughter relationship that was the main focus of the story. The post-apocalypse happening is very much in the background and I would have liked to see more of that instead of just in the last 15% of the book.
