Anathem gets my vote. It's a mystery, with things left for the reader to figure out. These things include where and when it's set, and what genre it's written in. A brilliantly apt form for a novel about science, which makes it hard to describe without spoiling it. The author has his usual fun. Historical inspriation: monasteries in the dark ages. Martial artists: far too cool for their own good. Tensor calculations performed as interpretive dance: it had to be done. The plight of hackers and scientists in a violent, greedy world strikes as true as ever. Stephenson's neologisms are a bonus. The principle "'X would be nice' does not imply X" needs a name, though I don't expect "Diax's rake" to stick. Also useful is "Lorite", for a scholar who specialises in refuting claims of novelty.
