It is okay. I like that is mentions other books. I now have a list of books I would like to read because of it.

I starts out a little slow, but then it is awesome book. Lots of excitement. Lots of action. It is kind of like Harry Potter meets the X-Men

This book is awesome! It is action packed. It reminds me of the movie national treasure. Love the mystery and puzzles of the book. I can't wait to read the next one.
