I'd suggest For a Prosperous World. It's one of the more unique stories I've ever come across because it tackles the subject of immortality in such an interesting way. It is a genderbender, but that has the added side effect of eliminating any romance in the novel (which would have been misplaced anyways), and while there's a bit of wuxia in it, it only exists in bite-sized amounts. I'd also suggest the book I'm currently reading: "Moscow in Flames". But I suspect it won't work for you. Thanks for saving me from these. Why the hell don't people mention this kind of thing when they talk up these books?
