Book excerpt: This Very Short Introduction chronicles the trends and traditions of modern Latin American literature, arguing that Latin American literature developed as a continent-wide phenomenon, not just an assemblage of national literatures, in moments of political crisis. With the Spanish American War came Modernismo, the end of World War I and the Mexican Revolution produced the avant-garde, and the Cuban Revolution sparked a movement in the novel that came to be known as the Boom. Within this narrative, the author covers all of the major writers of Latin American literature, from Andr?s Bello and Jos? Mar?a de Heredia, through Borges and Garc?a M?rquez, to Fernando Vallejo and Roberto Bola?o.
