"East of Eden" is a novel by Nobel Prize winner John Steinbeck, published in September 1952. Often described as Steinbeck's most ambitious novel, East of Eden brings to life the intricate details of two families, the Trasks and the Hamiltons, and their interwoven stories. The novel was originally addressed to Steinbeck's young sons, Thom and John (then 6½ and 4½ years old, respectively). Steinbeck wanted to describe the Salinas Valley for them in detail: the sights, sounds, smells, and colors.

Adam – newly wed and newly rich – now arrives in California and settles with the pregnant Cathy in the Salinas Valley, near the Hamilton family ranch. Cathy neither wants to be a mother nor to stay in California, but Adam is so happy with his new life that he does not realize there is any problem. Shortly after Cathy gives birth to twin boys, she shoots Adam in the shoulder and flees. Adam recovers but falls into a deep depression. Cathy gives birth to twin boys she names Aron and Caleb, who grow to have vastly different personalities.

The book explores themes of depravity, beneficence, love, and the struggle for acceptance, greatness, and the capacity for self-destruction and especially of guilt and freedom. It ties these themes together with references to and many parallels with the biblical Book of Genesis (especially Genesis Chapter 4, the story of Cain and Abel).
