Recommend a book on GC?

[HappyGoLuckyGo]

I'm increasingly interested in gender critical theory. Can anyone please recommend the best book they've read on the topic? Preferably available on Kindle? :)

Feminist chat gets more traffic FYI

Cordelia fine's work

Sheila Jeffreys - beauty and misogyny then Gender Hurts

I like 'all the rage' as a collection of essays that predates the current fads.

Audre lorde is fab on bdsm which links in - 'it's not about condemnation'

Thanks for your suggestions! Will ask the post to be moved.
