The Gate to Women's Country by Sheri S. Teper
around 85% of the way through; it's homophobic, transphobic, arguably misandrist ... yet I'm having a hard time not enjoying a fantasy world where misogyny is subverted and eliminated ... call it a guilty pleasure.
(EDIT: finished the book last night, I liked it, but I probably wouldn't recommend it simply because it is so reactionary. Definitely wouldn't want people uncritically adopting similar views, lol.)
