The sudden success of the Boom authors was in large part due to the fact that their works were among the first Latin American novels to be published in Europe, by publishing houses such as Barcelona's avant-garde Seix Barral in Spain. Indeed, Frederick M. Nunn writes that "Latin American novelists became world famous through their writing and their advocacy of political and social action, and because many of them had the good fortune to reach markets and audiences beyond Latin America through translation and travel—and sometimes through exile."
