I've just spent the evenng playing Blokus, a board-game that combines the best of Tetris and Go. It was ferociously addictive and fiercely competitive. Play with three others for maximal heart-wrenching tension between the need to attack and to defend. Of course, you can play online, too.

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.
