I'm pretty sure that this book is fine had a check through. No language apart from crap damn. Extremely mild. Good book for children who want a horror book but can't get one because their inappropriate. No Gore. Just don't let your child read this at night.
Its a really good book its all fine no nudity or anything like that. Its a bit scary has a lot of violence but not much blood. And in the scenes where there is blood its not described. Only a few scenes with blood great read. Suitable for ages 10+. I'm not sure why commonsensemedia is saying gory 14+ lots of language. Its not true. Read this book suitable for ages 10+. I am very protective about what my children watch or read. And this is fine so definitely let your children read this if they don't get scared easily.
