Why this Book?

For my literary analysis I chose East of Eden by John Steinbeck.  I've always enjoyed his books and I was curious about this one.  A couple weeks ago I found it in my garage and cracked it open.  I enjoyed the first couple chapters and read just a little bit every night.  Soon after that I find out that I need to choose an AP novel to read for my literary analysis.  Obviously I went with the book I had already started and enjoyed. So far it has been a good decision.  When I read Steinbeck, the pages turn themselves.
