Finished Dan Simmons's The Fall of Hyperion last night. What a brilliant book.
The two Hyperion books together form one of the greatest stories I've ever read. In the first book we were given the space opera story, the cyberpunk story, the military SF story, the SF horror story...etc. as individual, separate stories. I think in my post after having finished reading it, I called it Simmons's Ode to SF (or something to that effect). In this book, The Fall of Hyperion we are again given those various sub-genre stories, but this time they are united into one massive, conceptually staggering tale. There's really nothing else like it that I can point to.
Maybe the best way to sum it up: [Kwatz!]
