The bad news is that Tee Fury hasn't sold this smashing Obey Cthulhu/Coca Cola tee since July. The good news is that you can vote for them to bring it back. Vote!
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.
