[Fathom Zero]

I've read every book up until the last few hundred pages because I don't want to get to the ending.

I didn't like IV too much because it was all about backstory and crap that it really made no difference to know.

I guess this is King's magnum opus. A LOT of things are tied up in the book that relate to King's other books, I was suprised at how attention was paid to even the smallest connections between the books and Hearts in Atlantis, especially.

Besides, I think it's in comic book form now, anyway. I haven't read them, but I need to.

I think you should read them, though my opinion might not count for much.
