Europe in Autumn is a near-future sf novel by Dave Hutchinson. It’s set in a fragented Europe where nations are being created by squatters and rail lines and the borders to travel between them also proliferate. Rudi is an Estonian cook who gets recruited into an organization that hates these borders and does its best to get people and material through them. It has a bunch of oldschool spy tradecraft that Rudi finds ridiculous at first, but gradually becomes more useful as the plot deepens.
Though it was more of a technothriller, it reminded me of China Miéville’s The City & the City, one of my favourite detective stories. I’m looking forward to picking up the sequel.
