Spitbank Fort is an offshore island fortress built in the mid-Victorian to help protect Portsmouth. It's been renovated by some savvy hoteliers who've turned it into a luxury hotel and conference centre, and it's all rather gorgeous. You can book the whole thing for retreats, weddings, etc, or just book an individual room.
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.
