Excellent novel about a young man drafted into a courier network that relies on old-school spy tradecraft to cross the borders of a balkanised future Europe. His induction, training and early missions all seem to go catastrophically wrong, but he survives and even thrives in the strange, often boring, occasionally dangerous twilight world. I liked how as the book goes on, new sections begin eliptically with new settings and characters which intersect with Rudy's, as if he is becoming better at concealment until ready to reveal himself, and crossing the borders of other people's stories. After an almost meandering, episodic, but always interesting first half, things start to come together and then take a serious swerve towards something even weirder in the final quarter, leaving me looking forward to reading the rest of the series quite a lot.
