I'm a big fan of his work. In fact it was largely the experience of reading his books in high school that inspired me to attempt some creative writing of my own. His books "rock" in a way that most other literature doesn't. He also has a knack for setting up these perfect little scenes that you'll remember for the rest of your life. The end of the Dark Tower series, as provocative and controversial as it may be, is certainly not something I am ever going to forget.
