I read a lot of Stephen King books. And yes, I'm currently addicted to The Gunslinger series and can't wait for the next one to come out.
Most of King's books are entertaining, if not predictable. But The Stand was a masterpiece. I read it day and night for three weeks. It was one of the few books I got lost in. So much so that as I got towards the end, I was sorry that it was soon going to be over.
It's the only King book where I actually wondered what became of all these characters and where and how they ended up.
