— A sweeping, comprehensive epic, Hopeful Monsters tells the story of the love affair between Max, an English student of physics and biology, and Eleanor, a German Jewess and political radical. Together and apart, Max and Eleanor participate in the great political and intellectual movements which shape the twentieth century, taking them from Cambridge and Berlin to the Spanish Civil War, Russia, the Sahara, and finally to Los Alamos to witness the first nuclear test.
— Hopeful Monsters received Britain's prestigious Whitbread Award in 1990.
— Praising Mosley's ability to distill complex modes of thought, the New York Times called Hopeful Monsters a "virtual encyclopedia of twentieth century thought, in fictional form".
