Update: Danny adds, "the full price is four quid, but there's a quid off if you're a blogger (and not already under 18, a student, unemployed, a journalist, an old age pensioner, or any combination of the above). what more reason do you need to finally kick up that livejournal account and start selected your 'mood'?"
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.
