''There is only one book to a man'' Steinbeck wrote of East of Eden. Set in the rich farmland of the Salinas Valley, California, this powerful, often brutal novel, follows the interwined destinies of two families - the Trasks and the Hamiltons - whose generations hopelessly re-enact the fall of Adam and Eve and the poisonous rivalry of Cain and Abel. Here Steinbeck created some of his most memorable characters and explored his most enduring themes: the mystery of indentity; the inexplicability of love, and the murderous consequences of love''s absence.
