looking for reassurance here. I only discovered Stephen King in the last few years - I always thought I would dislike him because of the horror element but I read The Shining and was hooked. I haven't read any of the Dark Tower series but read on here that they were brilliant. So I've started with the Gunslinger and am finding it pretty hard going.
Do I absolutely need to read it to make sense of the others?
Do the others get better?
