Bests & Worsts Reviews from Amazon

My son has followed this series since he was 9; always eagerly awaiting the next. He said the book was ok... but was disappointed in the fact two of the female characters were joined in a relationship. He finished the book in one day and says the book focused on that relationship. To him it just didn't make sense. He's not so eager to get the next one and wants to return this one. Which is sad. He really has loved the series for so long.
