Insomnia

Insomnia is really a Dark Tower novel. I takes about 500 pages to get there, but then you are smacked in the ka with a tower, a dark figure, a king with guns on his hips, and the meaning of the whole struggle of the book as a footnote in the levels of the world. A fun read even if you haven't read any of the Dark Tower, there are moments where it drags. But at 700 pages, that's not a shock.
