This is one of my alltime favourite books, it combines very belivable and enjoyable charachters with a serious and tragic theme. It follows the fortunes of the Joad family as they migrate West in search of a better life. It also explores the rapid commercialisation of the West during the 20's as well as people like the Joads whom it left behind. Steinbeck breathes life into this case example family and I found myself with several favourite charachters, something I have not found in a book for a long time. Despite the poverty and sad theme of the book the strength of human spirit and hope emerges throughout the book. We can and should take lessons from this book, and the crude new greedy culture that is emerging during this novel is now ever too aparent in our society too. The introduction by Brad Leithauser is helpful for understanding the themes and background of the book, but I would not class it as esssential and it could of been explained in much more detail. If you enjoyed 'Of Mice and Men' you will love this, it is definitely Steinbecks masterpiece. All in all it is a very rewarding and un-put-downable book and I would recommend this book to everyone.
