Query: Unconventional masterpiece of its time

I was really impressed by the characters and themes that Steinbeck drew and tackled in this novel. I was blown away especially by the character of Lee since he plays such an important role in the novel and he's Chinese. At the time of the novel and its publication, I could not think of characters in novels or in film where minorities were not caricatures or stereotypically portrayed, so I was really surprised to find Lee so well drawn out. He was such a significant moral force in the story.I've read Steinbeck's other work and this is his masterpiece. For 600 pages, you get to live with these characters and it's sad when the book ends. The only thing to do is to reread and it's definitely one of those books worth rereading.
