Goosebumps was probably one of my favorite series as a child. I used to own the original 62. Now I'm going back through and doing a complete re-read. Monster Blood focuses on a young boy by the name of Evan who stays with his aunt while his parents search for a house. He buys a can of monster blood from the toy store and it begins to grow and grow at an uncontrollable rate. The reader spends most of the book following Evan as he attempts to control the growth of the monster blood. The writing is great for a younger audience. It's accessible and the small cliff hangers at the end of chapters will appeal to readers. I personally thought the ending was interesting but not a huge shocker. There was a double twist that I think kids will really enjoy and as always R.L. Stine leaves room for a potential second story to come out of this.
