I'm currently on The Dark Tower. It's the seventh book in a series by the same name. When I finish this one, I plan to start both Dante's Inferno and King's 'Salem's Lot. I've decided that since I'm enjoying the Dark Tower series so much, I'll read all of King's DT-related books. I've already read The Talisman, written with Peter Straubb, and I notice a lot of similarities. I can't wait to find out what happens when 'old long, tall, and ugly' gets to the Dark Tower.
