Parents, get your kids involved in this series! It is a mystery, a spy thriller, and a covertly educational choice for them. It has cross appeal for so many genre's, plus the online gaming appeal. The book is cleverly written, the educational stuff so discreetly tucked into the text that I didn't realize I was learning anything until a day later when I used a piece of trivia from this book in conversation! Boys, girls and adults who are kids at heart, this book is an entertaining read. There will be 10 books coming out from now until September 2010, so it is moving along fast enough to keep everyone engaged.
