In Final in Berlin, Heinz Rein leads the reader into the bowels of the city of Berlin, in April 1945, bombarded and plunged into total chaos, before the imminent collapse of Hitler and his family. Desperately, the Nazi regime tries to cling to power, and even in what would be its final days, the security forces and the Gestapo continue to sow terror, seeking Jews, dissidents and deserters. Mastering an atmosphere of paranoia and absolute suspicion, Rein recounts the situation of a small resistance cell, transferring readers to the very core of the collapse of Nazism, in a masterly novel whose main protagonist is the city of Berlin, in one of the most tragic and virulent periods of its long history.
