This is Steinbeck's most ambitious novel, and in his opinion, his finest work. ("I think everything else I have written has been, in a sense, practice for this.") My high school English teacher assigned us The Grapes of Wrath instead, so I didn't read this until a few years ago. The title references the fall of Adam and Eve, and the subsequent embattled relationship between brothers Cain and Abel. Grounded thoroughly in its California setting, interweaving the stories of two Salinas Valley families, Steinbeck's magnum opus feels tragic, yet hopeful.
