I started this book expecting a "serious" work of feminist theory. At some point I realized I had started on the wrong footing, so I reread it as a personal essay. That works way better. The book kiiinda presents itself as laying out a theory of gender (in short, the theory that everyone is female), but it doesn't really commit to that and the theory doesn't really work if you take it seriously - which I don't think the author wants us to. The book is actually an autobiographical reflection on the author's transition, told through her personal relation to Valerie Solanas' (tiny) body of work. I enjoyed it a lot!
