Defying Gravity

This isn't a book with lots of violence, war or death in it. There's enough of that in real life, and if you're into that kind of thing, then there's plenty of other books out there for you. This is a story about the stuff that we don't have enough of in real life. Love, tolerance, bravery and leadership. And its a story about humanity's first attempt to live in space, and how two young women save us all from our own stupidity.
Oh, it also features zero gravity, inter-racial, lesbian lovemaking.(Because there isn't enough of that in real life either)
