I'm halfway through book four right now, and I have to say this is quickly becoming one of my favorite series of books. I was never a big Stephen King fan 'til I bought The Stand at an airport bookstore last year and read the whole thing on my flight.
Anyway, I was wondering if there are any other Dark Tower fans on here. I know there's also a line of comic books out there that they recently started making (a few months ago, I think). The first book, The Gunslinger was a little hard to read. I didn't really like the writing style but he apparently wrote it when he was young, and the second book has a lot more fluid writing style (at least in my opinion). Also, if I remember correctly, he wrote what is now The Gunslinger as serials for a magazine, which may explain why the later books (which were written as books) flow better.
