I enjoyed Regenesis
every bit as much as its predecessor Cyteen
. I'm impressed by the way Cherryh presents the ethical issues around the azi (genetically and psychologically engineered humans)--which is to say, how she leaves them lurking in the background, because of course to the characters what they're doing is normal. As a reader, I get lulled into thinking that it's normal as well, so much so that when one antagonist character launches into a speech towards the middle of the book decrying how "one woman is imposing her mental design on the whole human species" my initial reaction was to roll my eyes along with the rest of the characters and wish he'd just get with the program. But of course, he has a point. . . .
