East of Eden
Steinbeck's family saga in the Salinas Valley explicitly parallels Cain and Abel. The word "timshel" (thou mayest) becomes the philosophical anchor: choice, not fate, not God, is the gift and burden of human life. Readers consistently name it the book they think about most. Steinbeck called it his magnum opus; critics disagreed. The readers were right.
Cathy is born a monster in a novel whose entire sermon says people choose; Steinbeck breaks his own thesis to give himself a devil. He narrates in person, moralizes at will, and hands Lee the timshel lecture like a seminar leader. The Hamilton chapters wander away from the Trasks whenever they feel like it. Generous, yes; disciplined, no.
The case for it and the rest of the canon open with Pro.
