I'm not usually one for novelty mugs, but the prescription coffee mug seems to reveal a deep and important truth about my relationship to coffee. It's kind of the caffeine addict's equivalent to the skull on a poet's desk: a reminder of your own mortal fallibility.
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.
