Cujo was a surprisingly good read. I thought I knew what it was about beforehand (crazy dog), but it really comes at the situation from an interesting angle. It also doesn't completely take place in the car as I had assumed through vague pop culture references. I've never seen the movie, so maybe that takes place mostly in the car? The book follows many characters and the events that lead up to the car and beyond. 

The setting for Cujo is Castle Rock, Maine, which was also featured in The Dead Zone. I would recommend reading The Dead Zone before this one if you're interested in spotting any connections. However, it's not necessary to read any other King before you read Cujo. 

The ending caught me by surprise. I was thinking that this book was sorta boring and average for King in story telling before it got real. It's going to be hard to forget. I would recommend the read.
