I was excited by the idea of this book: a near-future woman scientist's discovery of some paradigm-shifting biological sex genetic thingy. And I read the whole thing straight through (have a cold) but what I came away with was that Jones's characterizations are bizarrely homophobic and even misogynist. Certainly Jones is willing to have the one lesbian character in the book be an avowed woman-hater and the one "lesbian" sex scene is as bad as some kind of 80s-era Naiad Press romance: "...they got naked and lay between them, and hugged and kissed and nuzzled and licked and enjoyed each other..." All non-gender-conforming and/or queer people in this novel are characterized as freaks, unstable, immoral, frivolous, or ugly. Seriously? This won the James Tiptree prize?
