I loved that along with the usual creative stories of the whole series, this book finally gave solutions you've been waiting to discover. There is mystery, action, a tiny bit of romance, and kids getting old enough to experience some grown up feelings. This being the fourth in the series, you care about the characters because you really know them. Just a wonderful experience and great writing. I never imagined I would be saying this about anything "Harry Potter." Not just for kids, definitely.
