Hailed for its humanity and power, this odyssey of the Okies as they took flight westward from their dust-ruined land will long remain an important social document. As a fictional account of a migration unique in American history, it will endure as a magnificent work of literature. The Grapes of Wrath is the novel by which John Steinbeck achieved his greatest fame. It is one of four of his books on the Modern Library shelf. The other three are Tortilla Flat (No. 216), Of Mice and Men (No. 29) and In Dubious Battle (No. 115).
