What parents can learn from the books their children read

The New York Times Well column had an article today about what parents can learn about the lives and thoughts of their children from a popular book series. The article highlights the series Diary of a Wimpy Kid. The books talk about the regular struggles of a regular kid, a kid to whom readers can relate. The stories give insight into how a child struggles internally with issues of fairness and ethics and relates how a child works through these dilemmas, not how an adult thinks a child should work through them.

For many families, the books are serving as a catalyst of discussion between parents and children. What other books might help spur family communication?
