Query: After the first 3, the 4th is quite boring and redundant.

As the series progresses, more and more 'mysticism' becomes the driving force behind the book, thus getting further and further from an entertaining, perhaps educating, story.Also, the constant regurgitating of facts for a reader that has not read the previous ones wears thin.The series should have been 1 book--I think the author's profits or delusions of a 'saga' series ruined it. I can't read the last 50 pages--I'm completely bored.
