Would you let a 9 year old read Bram Stoker's Dracula?
It's a long time since I read it, but from memory the 'raunchy' bits are implied rather than explicit. I'm not concerned about him getting scared as he's very able to separate fiction from reality. Generally in life anything 'inappropriate' just goes straight over his head.
He has a reading age of 16+ and has read the Lord of the Rings books, so I'm sure he could understand it. Just wondering whether content-wise he might be a bit young?
Reason this has come up is because he's been reading the Skulduggery Pleasant books and interested in finding out more about vampires :)
