The 39 Clues series of 11 books are fascinating for all ages.The characters are always emotional in different parts of the books. The main characters are two kids named Amy and her younger brother Dan.They are two orphaned children that are being raised by their aunt and that have just lost their grandmother. When they go to her funeral, their grandmother's executor reads out a will and they are thrown into a perilous adventure. They must collect 39 clues along with other teams and be the first to reveal a secret that will turn them from orphaned kids to the most powerful people in the world. These books have been written by different authors that have gathered up their imagination and imagined the stories. I have enjoyed reading the books and hope that there are more to come in the future.
