Query: Harry's back and better than ever!

In her long awaited return to Harry Potter and his gang of Hogwarts fellows, Rowling outdoes herself! 800+ pages fly by in an exhilarating read that shows Harry, Ron, and Hermione more mature, but irrepressable as ever in their continuing quest to defeat Lord Voldemort.This book is more mature than Rowling's last, which may cause parents to want to read it with their younger children, discussing weighty matters such as unfairness, ridicule, and death.
