The maze of bones

Hey guys! I have been reading the 39 clues series ( This note is only for 39 clues fans: a new series came out in August called Cahills vs. Vespers. Book 2 arrives in December. ) It is a pretty solid book, but Dan can be annoying in some parts :) I like how Riodoran wrote this book, well, I like how all of the authors are writing them so far. If you want to learn about history and important historical figures, this is the series for you. WARNING : SPOILER ALERT!!!!! In the first book, Amy and Dan find out that they are members of possibly the most important family in world history. The get a clue whick leads them to France because Ben Franklin was a Cahill and went there.They get a bunch of clues and are then, finally, lead to the famous Paris catacomes. However, They get lost.At the end of the book, they emerge from th catacomes with the clue for this book. I will not reveal the clue, but I will provide a link to a website with the clue. Do not read anything else, as they are the clues to the other books. http://en.wikipedia.org/wiki/The_39_Clues
