The German author’s latest novel is about as plausible as any fast-paced thriller — which is to say, not very. It’s also a dystopia, as dark and funny as the genre gets. Protagonist Britta runs a website that links up the deeply depressed with organizations in need of suicide bombers, which makes a little more sense in 2025, by which point the EU has fallen apart and sinister populists run Germany. Britta is forced to go white-hat when confronted with a competitor who threatens far more than her livelihood; as in the real world, sharp turns and painful choices lie ahead.
