The Century's Midnight is an exploration of the literary and political relationships between a number of ideologically sophisticated American and European writers during a mid-twentieth century dominated by the Second World War. Clive Bush offers an account of an intelligent and diverse community of people of good will, transcending national, ideological and cultural barriers. Although structured around five central figures - the novelist Victor Serge, the editors Dwight Macdonald and Dorothy Norman, the cultural critic Lewis Mumford and the poet Muriel Rukeyser - the book examines a wealth of European and American writers including Hannah Arendt, Simone de Beauvoir, Walter Benjamin, John Dos Passos, André Gide, Henry Miller, Anaïs Nin, George Orwell, Boris Pilniak, Albert Camus, Jean-Paul Sartre, Ignacio Silone and Richard Wright.

The book's central theme relates politics and literature to time and narrative. The author argues that knowledge of the writers of this period is of inestimable value in attempting to understand our contemporary world.
