We have received the first book in the 39 Clues series -- The Maze of Bones by Rick Riordan. I haven't been able to read the book yet, but I have already started to unlock some of the clues. I visited the 39 Clues website and created my own account. Once you pick a username and password, you are asked to answer a few questions, for example: Would you rather have a star on the Hollywood Walk of Fame or have a real star in the sky named after you? My answers put me in the Ekaterina Branch of the powerful Cahill family. If you're a member of the Tomas branch -- sorry, but you are now my sworn enemy! Each week you get four messages in your inbox to help you unlock clues and bring you closer to the prize money! Some of the clues are easy, some are hard, but all are time-consuming. Solving the 39 Clues could be a full-time job.
