My votes are mood-dependent! *g* If you want awesome SF with mind-bendy gender stuff next, go for Left Hand of Darkness; if you are more in the mood for a slash/snark/politics trifecta, go for Swordspoint. (Cannot speak for The Persian Boy, as I am inevitably/eternally? in a LA LA LA THERE WILL BE NO BREAKING OF MY ALEXANDER/HEPHAISTION OTP mood post-Fire From Heaven... but I did enjoy Fire From Heaven!)
