Coming of Age Stories

Recently, I was asked to think of some of my favorite books on change.  I immediately thought about all of the Middle Grade and Young Adult novels that I read and how for the most part change is discussed in the terms of "coming of age or growing up.  This got me thinking and I decided to do a short survey to see what are your favorite coming of age novels.  Based on the responses, I will do a follow up post on the topic.  Thank you in advance for sharing your favorite titles.
