Only Stephen King book I've enjoyed. Behind the scary story - and, oh god, is it scary ! -, there's a melancholic tale of childhood and coming of age. It's a surprisingly good book. Cons: Really bad movie adaptation. You'll probably never be able to see a clown anymore without shivering.
Only Stephen King book I've actually read. Scared the pants off me, surprisingly Lovecraftian. Cons: If, like me, you actually somehow ENJOYED the old TV miniseries, the novel will definitely mostly ruin it for you.
