I very much liked Susan Maushart's 'Wifework'. She's a sociologist and the book examines very fairly the lives of working wives in comparison to that of their menfolk. (feminist, obviously)

I recently bought a copy of her sequel, 'What Women Want Next' which is thoughtful and balanced. It examines where Women's Rights has brought women now, and whether we are actually happier.
She refers at all times to recognised research studies and her conclusions are most interesting.
