The Couriers: The Complete Series collects four short stories from early in Brian "DMZ" Wood's career, involving a pair of courier/ninjas who run parcels for crime syndicates, shady characters, and other nonstandard enterprises. They're armed to the teeth, hyper-violent, skillful, wisecracking, and remorseless. Think of Kick-Ass crossed with Run, Lola, Run. It's lovely stuff, and the art conveys that Taratino-ey balletic violence in a way I'd never have suspected was possible without actual moving pictures. This is silly and fluffy, but witty and well-told, and it's the kind of stuff you can't stop reading once you've started.
As a bonus for Brian Wood fans, Image Comics has just brought out issue one of Mara, a new, six-issue future-dystopic tale drawn by Jordie Bellaire & Ming Doyle, which starts very strong.
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.
