KINFLICKS by Lisa Alther is okay, if I remember right, in a 60's/70's self-discovery kind of way. And there's Mary Renault's TWO FRIENDLY YOUNG LADIES. Sort of. (Bonus points for the houseboat, and for a very excellent farcical scene in the middle with people popping in and out of rooms and just missing various indiscretions, but marked down for a certain skirting of the subject and an excess of repressed British WTF-is-going-on-here-exactly?)

I like Empress of the World better than either of them, though.
