Update: A Boing Boing reader has produced "a Bullshit Protector PDF that looks as close to the original photo as I could make it. And, yes, it really does say "cooties"."
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.
