39 Clues

Once Amy and Dan Cahill's choice was simple - take a million dollars or the first of 39 Clues that lead to the source of unimaginable power. Now it's clear that the hunt for Clues is bigger than anything that Amy and Dan could ever have imagined.

As the race to find the 39 Clues builds to its explosive finish, Amy and Dan must steal a Clue guarded by thousands of the world's best soldiers. With their enemies closing in, the siblings are separated. Together, they almost have a chance, but alone.... Could the search for this Clue spell the end of Amy and Dan?

A hint from their parents' past puts Amy and Dan on the trail of secrets their grandmother Grace would NEVER have wanted them to know. Awful memories begin to crowd in on Amy, just as her enemies circle closer. How far would she go to protect Dan? How much of a Cahill is she prepared to be? Perhaps Grace was right - some secrets are better left buried.

There's only one rule in the race to find 39 Clues hidden around the world: TRUST NO ONE.
