On the always-excellent How to Be a Retronaut site, a great collection of 1960s fallout shelter ads, a perfect capsule of upbeat, cheerful fear-selling.
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.
