Have about 50 pages left,
just enough for sitting in the warm shade with a beer and taking in the last tasty morsels. Saving it for just such a moment.
Have you read Stephenson before? This latest is not my favorite of his yet I've enjoyed his pushing into the fantasy genre. As ever with Neal, the story is rooted in hard scifi, ancient religions, and classic literature; all with a descriptive prose and slightly Pynchonesque syntax. And if you are familiar with his work you'll quickly see this as a continuation of his charcters' multi-tome arcs. Completely stand novel, though.
Hope you enjoy it and look forward to hearing your impressions.
