Considered by some the heir to the early Robert Heinlein's libertarian SF brilliance. This assumes a) that you know so little of Heinlein that you think he was a libertarian, and b) that you think it's meaningful or interesting to group authors by their political convictions. Both assumptions are cretinous. Hugo and Nebula Award winner. Author of the Gaean Trilogy (Titan, Wizard, Demon). Recent novels include The Golden Globe and Steel Beach set in our solar system when Gaseous invaders have wiped earth of human life and given it to the dolphins. Can actually write about sex like it's something normal even when it's not.
