The 39 clues – Rick Riordan

The 39 Clues centres around the Cahills—the most powerful family the world has ever known.

The source of its power is a mystery that can only be unraveled by assembling 39 clues hidden around the world throughout history.

The spellbinding first book (Book #1: The Maze of Bones, September 2008), by Rick Riordan,

author of the New York Times bestselling Percy Jackson series, will be followed by a team of best-selling and acclaimed authors,

including Gordon Korman (Book #2, January 2009), Peter Lerangis (Book #3, April 2009), and Jude Watson (Book #4, July 2009).

Additional authors and publication dates for subsequent titles will be announced at a later date.
