If there's one thing I love, it's irising mechanisms. And if there's another thing I love, it's thick-framed glasses. That's two things I love, and as you've probably guessed, there's someone who's combined 'em.

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.
