Dark Roasted Blend's roundup of civilian-accessible spy gizmos will be largely familiar to attentive readers of this blog, but it's nice to have all this stuff in one place, from the hollow coins to the pens that turn into deadly! stabby! knives!
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.
