In the Boing Boing store: Zombie Sleep Masks. One of these is going in my "most comfortable man in the sky" airplane kit -- a carry-all with a tiny two-temperature sleeping bag, hot water bottle, fuzzy sleep socks, freshly pressed cotton pyjamas, and a sleep mask.
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.
