Stephen King Books for a 13 year old

[bing]

Guys,

My son has an interest in Stephen King books and has been told that he can read one as part of a school project.

Now I'm not too clued up on them but I know from the movies and TV shows that they're not particularly kid friendly.

Any recommendations on SK books that may be suitable for a 13 year old boy? He's pretty mature etc for his age.

He wants to read Pet Cemetery, but after reading the 'synopsis' I'm not sure it's right.

There's a few recommendations here:
