As for me I was really impressed by "The Dark Tower". This book is not just an example of horror genre (as we often think recollecting King's works). It's more of fantasy. This series of books kept me rooted till the end. If you haven't read this story yet, do it! You won't be disappointed.
Universal has canceled its planned film-and-TV adaptation of Stephen King’s The Dark Tower book series- a sad news(. I was really looking forward to it!
Almost every King's book is amazing! However his book "The Shining" is my favourite, for me it's his the best book :)
I haven't read a lot of books of him, but among the ones I have, "Rose Madder" is my favorite. :)
