I love this book - I actually listened to it as I was needing something to listen to at the gym and I borrowed the audio book from the library thinking it was another book that I owned, but hadn't had a chance to read yet... So glad I made the mistake - most interesting book I've read (ok listened to - although I have the physical copy now) in years. Really insightful in terms of how our society sees identity, how we see it in ourselves, the origins of those identity types, and how they came about (and how made up they are).
