heh... Lot of politics involved with gene manipulation and cloning

Me, I'm more of a fan of her more space opera'ish stuff, Chanur, Tripoint, Merchanters Luck, Heavy Time, Rimrunners but those are all in the same universe with Cyteen and all rigorous in their science too.
But I like socialogical implications of science presented as well as just the science. And part of that can be political. And I like my science extended to it's implications. So I like my recommendation.
