those are good versions too, with the illustrations. I don't understand why they ever published any of the Dark Tower without illustrations.
And yeah, The Shining is a good crossover recommendation for people who aren't into horror. It's just undeniably great, and not too intense really. The Shining is like King in PG-13 mode, but it's a masterpiece. By comparison, stuff like IT and Needful Things are super hard-R rated. My grandfather gave me a copy of Needful Things when I was 12... and clearly he did not read it. The first time I read that book I was wayyyyyyyy too young for it.
