Tom felt his darkness. His father was beautiful and clever, his mother was short and mathematically sure. Each of his brothers and sisters had looks or gifts or fortune. Tom loved all of them passionately, but he felt heavy and earth-bound. He climbed ecstatic mountains and floundered in the rocky darkness between the peaks. He had spurts of bravery but they were bracketed in battens of cowardice.

The book is very different in tone from Steinbeck's amoral and ecological stance in earlier works like Tortilla Flat and Cannery Row. The story is about two traveling ranch workers George and Lennie trying to work up enough money to buy their own farm/ranch. Soon after he began work on East of Eden (1952) which he considered his best work.
