One of today's foremost Steinbeck scholars writes an extended meditation on the influence of "The Grapes of Wrath," to commemorate the 75th anniversary of its first publication In this compelling biography of a book, Susan Shillinglaw delves into John Steinbeck's classic to explore the cultural, social, political, scientific, and creative impact of "The Grapes of Wrath" upon first publication, as well as its enduring legacy. First published in April 1939, Steinbeck's National Book Award-winning epic of the Great Depression chronicles the Dust Bowl migration of the 1930s and the story of one Oklahoma farm family, the Joads, driven from their homestead and forced to travel west to the promised land of California. The story of their struggle remains eerily relevant in today's America and stands as a portrait of the conflict between the powerful and the powerless, "in the souls of the people."
