The steampunk graphic novel is The Invention of Hugo Cabret by Brian Selznik, which tells the story of "an orphan in early-20th-century Paris living inside the walls of a train station, trying to finish an invention left by his father. The ALA Caldecott site says 'the suspenseful text and wordless double-page spreads narrate the tale… which is filled with cinematic intrigue.'" I've just ordered my copy.

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.
