Incoherently

... You can not call this book. After all, it creates the author this time, to tell a coherent story. Was it been in the previous volumes (as in children's books available) sent by a minor episode in the next, which then eventually showed a whole book, this time it has managed to portray a continuous storyline. So stylistically a definite improvement on the previous books in this series.
Unfortunately, this continuous action is dearly bought. The author manages Although the (einzen considered) ordinary ideas into a story put together, unfortunately at the expense of any logic and credibility for HP conditions.
Every time a particular circumstance is required for the continuation of the story, the Ministry of Magic has to serve, and make the most incredible choices to have and attract, this comparison is bad enough, remember almost to stasis or Nazi methods! And these decisions are involuntarily accepted by the "good" of the book, so the story goes beautifully exciting.
Very questionable, what message is being communicated to the younger readers so if indeed repeatedly spoken of resistance, but just people like Dumbledore to lift a finger.
Otherwise hardly deviated from the usual order in the books. Quite amusing is the newly pubescent Harry. Unfortunately, you have approx. 300 pages wait really begins the action.
In summary, one can say that this book is highly recommended, as long as you do not fear too much excited about the thoughtlessness of the author.
It will be important in any case, with younger children read this book, to talk about the behavior of the Ministry and of acting in this novel adult.
