Are there any NON-TERF radfem authors you like?

I don't consider myself a radfem (and nowhere near being a TERF thank fuck), but find myself agreeing with radfem sentiments when I stumble into discussions about feminism online.

I'm looking to start reading more non-fiction philosophical and social ideology books, and would love to see what books/authors everyone likes that relate to radical feminism. Plus points if they're sapphic!!
