Now this looks like a book worth reading: "a collection of essays that manages to revel in everything ever done by the first openly gay, feminist spitfire of fantasy and speculative fiction." (Rest of the Voice review here.)
Ammonite would not exist without Joanna Russ's work. Her collection, Extraordinary People, is sharp and deep and deliciously sly. At some point, everyone should read her brilliant novella, "When It Changed." (Though if it were written today I might take issue with it.) Linked to that novella, of course, is her most famous novel, The Female Man. Don't know her work? What are you waiting for?
