With the publication of his seminal novel White Noise, Don DeLillo was elevated into the pantheon of great American writers. His novels are admired and studied for their narrative technique, political themes, and their prophetic commentary on the cultural crises affecting contemporary America. In an age dominated by the image, DeLillo's fiction encourages the reader to think historically about such matters as the Cold War, the assassination of President Kennedy, threats to the environment, and terrorism. This Companion charts the shape of DeLillo's career, his relation to twentieth-century aesthetics, and his major themes. It also provides in-depth assessments of his best-known novels, White Noise, Libra, and Underworld, which have become required reading not only for students of American literature, but for all interested in the history and the future of American culture.
