The 39 clues is a sensitively written series about two orphans (Amy and Dan Cahill) who embark on an adventure to find the 39 clues and become the most powerful in the world. There are many obstacles along the way and the four branches will stop at nothing to win. Along the way the orphans discover some of the most famous people in history were Cahills. They come close to finding the truth about their parents and what branch they belong to.
This series is written by different authors but continues along the same lines. I would recommend this book to anyone who loves action-packed mystery books. There are 11 books in the series, each with an exciting new plot. The cover might be a bit misleading and some wouldn't get a second glance, but it really does prove the point - don't judge a book by its cover. By NL
