I just finest the book the 39 Clues, The Maze of Bones. There are ten books in this whole series and the cool thing is that all of them are written by all different authors so you get a feel for a different witting styles. The first book is written by Rick Riordan who wrote the Percy Jackson and the Olympians series. If you have read the Artemis Fool books, another good series, it is a lot like that. I t is about two kids who go on this big clue hunt to become the most powerful person in the world. If you read the first two pages you will end up reading the rest of the book and the whole series.
