Neal Stephenson and Nicole Galland's DODO novel mashes up D&D, time-travel and military bureaucracy

While all of Neal Stephenson's -- always excellent -- novels share common themes and tropes, they're also told in many different modes, from the stately, measured pace of the Baroque Cycle books to the madcap energy of Snow Crash to the wildly experimental pacing of Seveneves. With The Rise and Fall of DODO, a novel co-written with his Mongoliad collaborator, the novelist Nicole Galland, we get all the modes of Stephenson, and all the tropes, and it is glorious.
