I saw some people saying that they thought it took too long for the book to get to the "exciting part". I personally loved the build up and thought it really gave some great background information for the characters.

King really is a master of descriptions, the world building made me feel as if I was there with Charlie. The characters were so interesting (including the dog) I have a German Shepherd so was excited to see one being in this.

I personally can't fault the book.
