DESC: John Steinbeck's last significant work of fiction (1952), a huge family saga based on the book of Genesis, is set in the Salinas Valley of the author's youth. Beginning with the purchase of a parcel of rich California farmland by Samuel Hamilton, who comes from Ireland with his wife, EAST OF EDEN traces the turbulent lives of the Hamilton and Trask families from the Civil War to the end of World War I. Adam Trask marries a prostitute who bears him twin sons--the Cain and Abel figures--and their rivalry shadows the second half of the novel, culminating in tragedy. Steinbeck had hoped to revive his failing career with this epic work, but though a best-seller, EAST OF EDEN was not well received by critics. However, because of its epic sweep and dramatic story, as well as its function as a virtual history of the Salinas Valley, the book has endured as an American classic. It was made into a memorable movie in 1955, directed by Elia Kazan and starring James Dean.
