In "Dungeons and Dragons, Satan's Game," we learn that D&D is a gateway to Satanism and human sacrifice. I remember being a young gamer in the early 1980s and meeting people who'd warn me about the peril it presented to my immortal soul.
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.
