Ur-atheist Richard "God Delusion" Dawkins, a staunch opponent of Creationism (even when tarted up as "Intelligent Design"), has recorded an audio edition of Darwin's "Origin of Species." It's been years since I read Darwin, but what better way to get reacquainted than through a reading by such an august personage?

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
