UPDATE: Mark sez: My favorite picture in this gallery is titled "Criticizing and Exposing Collaborators." It's a blatant rip-off of Norman Rockwell's famous "Freedom of Speech" painting! Link

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.
