Omega Minor by Paul Verhaeghen
Four narrative strands, seemingly unrelated, sometimes told consecutively in the first person (so the reader has to figure out who's speaking), encompassing 50 years of Berlin history, the Nazi regime, the rise of communism, and the Manhattan Project. Somehow, it manages to not fall apart under its great ambition, and reveals moments of great empathy and emotion. And sex, lots of sex. Nothing is what it seems, and no one, and the stylistic prose is absolutely compelling through all 700 pages. Winner of the Independent Foreign Fiction Prize and the Flemish Culture Award for Fiction.
