The Bone Palace by Amanda Downum (Orbit 2010) — noted for a deliciously complicated plot that challenges 21st century Earth attitudes toward transfolk. One juror noted that this book came closest among the honor list to meeting her Tiptree ideal by including a character that not only embodies a challenge to prescribed roles, but also creates a crack in or addition to the structure that carries forward to future generations.
The Hundred Thousand Kingdoms by N.K. Jemisin (Orbit 2010) — set in a matriarchal society where the privilege and expectations between the sexes are reversed, while the gender roles are different but recognizable (and believable).
“Diana Comet and the Disappearing Lover” by Sandra McDonald (published as “Diana Comet,” Strange Horizons, March 2 & March 9, 2009) — a (true) love story, in which the author does something simple but radical with the identity issues at play.
“Drag Queen Astronaut” by Sandra McDonald (Crossed Genres issue 24, November 2010) — a wonderful exploration (and ultimately an affirmation) of a gender presentation that tends to be ignored or ridiculed.
The Secret Feminist Cabal by Helen Merrick (Aqueduct Press 2009) — an academic look at the history of early feminism in science fiction, science fiction criticism, and fandom that provides a valuable documentation of our beginnings
Who Fears Death by Nnedi Okorafor (DAW 2010) —A strong female lead character breaks out of restrictive gender roles to change her life, perhaps changing history as a result. A well-written perspective on prejudice and discrimination and the lessons needed to overcome their bonds on our identities and imaginations.
Living with Ghosts by Kari Sperring (DAW 2009) — an unusual perspective in a main character —a feminized man who makes much of his living as an escort/high-class sex worker who sees ghosts when he is not expecting — or expected — to be able to do so. An excellent read.
The Colony by Jillian Weise (Soft Skull Press 2010) — Takes on the idea that pervades our culture that women have to be perfect in order to have sex with men. One juror notes: “I’ve never read a book that made a woman with one leg so sexually normal.” Smart and well written with subtle gender politics.
