Alice Walker, a writer who had generally shunned public life, reached a period of great achievement in the early 1980s. Her novel, The Color Purple, was awarded both the Pulitzer Prize and the American Book Award. But when Steven Spielberg made a film of the novel, intense controversy erupted. In this provocative and thoughtful collection of essays, Walker takes, as she puts it, a "lingering look backward at a dangerous crossroad in one"s life." How does a serious writer engage popular culture? What are the costs? What are the joys? The eloquent Ms. Walker offers insights.
