I read the first HP before most of the world even knew about it yet, as I was working in a book store, and have enjoyed the series tremendously. But I found this book a bit tedious. I thought most of it was just a rehash of the old stories. As with happens in many series, the author spent too much time, bringing back references or "guest stars" from the old books, and too little was actually spent on the mystery of this book. And when you know magic is involved, if something bad happens, you are never quite convinced that something magical undo the bad things. So the trustworthiness of this book is really in question. I really think this book should have been shorter and more time spent on the plot in question and not all the sidelines. A disappointment.
