Ever since a friend from work introduced me to Ursula K. Le Guin's Left Hand of Darkness, I've fallen in love with her exploration of gender and basic human interaction. I have not come across any other author who can twist the meaning of what it is to be a woman or a man. In that same token, Le Guin introduces the reader to concepts of marriage that are extremely foreign to our way of living. The best part about it, Le Guin wrote most of these stories well before my time.
Now I'm reading The Birthday of the World And Other Stories In this collection of stories she brings back all of her familiar worlds, concepts and builds upon each of her novels. I started reading this on the way out to Indiana last weekend and was surprised how quickly I took in the first couple of stories. I haven't felt completely enclosed in a fantasy world since my days at home reading my Star Trek or Star Wars books. In fact, I wish I had discovered Le Guin back then. Who knows, it may have made a bigger impact on my own sexual identity growing up.
