I am a big Neal Stephenson fan, starting with Snow Crash, a sci-fi classic. With Cryptonomicon, the author stepped into the world of historical fiction, using real people to help purely fictional ones break codes during World War II and hunt treasure in the present time. His "System of the World" series advanced that gimmick even further (and into many more pages).
Stephenson's new book, Anathem, is 960 pages long. I will be reading it for awhile. It is full of strange words that I must look up in its glossary -- yes, it has a multiple-page glossary and mathematical addendum.
So, I'll be gone for a while, immersed in a strange world of Stephenson's imagination.
