I see several people read Koontz and King, I love their work.
Unfortunately, I haven't had time to keep up with their new stuff... I did buy the latest King, and I was planning on reading it cover to cover (one sitting) over Srping Break, but I'll be moving instead.
I know that with Koontz and King I need to be able to just sit and read for at least 8 hours straight, because if I don't have the time to do it, I'll do it anyhow lol
