Rob Doyle reflects on the changing identity of Berlin, once known as Europe's licentious, experimental, ultraliberal techno capital. As the city becomes more expensive and gentrified, novels set in Berlin capture the moods and sensibilities of different eras, from the bohemian utopia to the tech and finance elite's playground. Authors like Leif Randt, Vincenzo Latronico, Nell Zink, and Aria Aber explore themes of gentrification, immigration, and societal shifts in their works, painting a Cubist portrait of a city in transition.
