“East of Eden” by Nobel Prize winner John Steinbeck is a journal about several families and two in particular that become close in a dark way. One of the families, the Trasks, is similar to the Biblical story of Cain and Abel. Steinbeck’s characters are fascinating in many realms, such as love, mystery and murder.
