I want to read some Stephen King's books, which do あなた recommend?

It all depends on what あなた want to read.
A must read is "The Stand" which is about a virus that wipes out the 99,9% of the human race and how the remaining survivors have to pick sides between the Dark and Good side of sth I can't tell あなた without spoiling you.
There's always "Salem's Lot", a story about ヴァンパイア in a small town, very scary and nothing like Twilight または "Needful Things" which is all about the vanity of people's lust for material goods and how a store can make your wishes come true.
If あなた want sth もっと見る emotional, there's the brilliant "Green Mile".
