J.K. Rowling should continue taking as much time as she needs to create each new installment of the series.The extra time she gave herself for Order of the Phoenix pays off with better writing and even richer characterizations.But the most stiking change is Harry. Adult readers may initially be irritated by Harry's teen angst, but as the story unfolds, you realize that A) you were 15 once and Rowling has simply allowed Harry to feel the anger and insecurity that most teens cope with on a daily basis and B) Harry is reacting understandably to the difficult experiences thrust upon him over the past four years.As for kids, well, it's a great book ... what's not to love.And most importantly, we finally get that elusive piece of the Voldemort puzzle - and the story finally moves into epic territory.
