Query: Frustrated by the short period covered and left hanging.

Please bear with me while I explain why I give this book such a low rating. I have read the entire series including this book. Don't get me wrong, the books are a quick and enjoyable read. I started the series in the summer of 2001 when there were only 8 books. I finished all 8 in about 6 weeks. But I am frustrated that at this point there may be 15 books to complete the series if they cover the small amount of time this one does. Also, without describing the ending of this book, it leaves you hanging in the middle of an episode. I am hooked and ready for the next book, but it will not be out until next year. My recommendation is to NOT purchase this book now. Wait until the entire series is completed and then buy which books you have not read all at once. That way you will have the entire story and can read it until completion and not be frustrated.
