The $30 kids' superhero raincoats come in Batman and Spider-Man -- but the Batman is the clear winner, with its own cape. Bonus: the logos glow in the dark.
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.
