The 39 Clues Sneak Peek!

Posted by at 3:30 pm in Reads, The 39 Clues | Permalink

The 39 Clues is special for many reasons. It’s the first book series that uses collectible cards and an online game to tell an exciting story: the secrets of the Cahills. The Cahills are the most powerful family in the world, and their members include people like Abraham Lincoln, Annie Oakley, and Albert Einstein. The source of the family’s influence has been hidden around the world in the form of 39 clues, and a competition has been organized to find them. The winners will become the most powerful Cahills of all, no small feat when your ancestors include George Washington!

The books follow Amy Cahill, age 14, and Dan Cahill, age 11, as they travel the world, solving the most important puzzles in history as they hunt for the clues. I love that each of the 10 books will be written by a different author — the “dream team” approach to storytelling. We were incredibly lucky to have Rick Riordan write The Maze of Bones. It’s full of Rick’s signature humor and adventure.

The 39 Clues is much more than a series of fantastic books. It’s an interactive adventure that allows you to uncover the secrets of The 39 Clues. You can buy 39 Clues Card Packs which contain 16 cards full of information about the Cahills. There’s also a website where you can research the Cahills and hunt for the clues. You can check out our site now:

Working on The 39 Clues has been a blast. I’ve always loved history, and it’s been so much fun to include the strangest, wackiest aspects of it in The 39 Clues. Ever heard the phrase, “Truth is stranger than fiction”? Well, it’s true . . . and the Cahills were involved with it all! I can’t wait for all of you to read The Maze of Bones, check out the cards, and play on the website. Do you think you might also be part of the most powerful family in history? Go find out at!

For a special head start on your hunt for clues, you can read the first two chapters of The Maze of Bones now! Check it out (PDF)!
