There's a complete Calvin and Hobbes hardcover archival collection (a la the totally stunning $100 Far Side box set from last year) coming out, priced at $150 (yowch, but man, how totally cool to own one of these!).

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.
