Book 1: Nowhere To Run
Amy and Dan risked everything on the hunt for the 39 Clues, but their sacrifices paid off. Now, the ingredients to Gideon Cahill's serum — the source of their family's historic power — are safely hidden out of harm's way.
Presidential candidate J. Rutherford Pierce has stolen the Clues and is using the serum to seize control of the country . . . and the world. It’s the Cahills' worst nightmare come to life — the Clues in the wrong hands.
The only way to stop Pierce is to create an antidote to the serum based on a secret recipe. There's just one problem: each of the ingredients has been missing for centuries, lost among the ruins of legendary cities like Troy. Amy and Dan Cahill have experience accomplishing the impossible, but they've never faced an enemy like Pierce before.
With time running out and enemies at every turn, the siblings set off to find the ingredients before it's game over. For everyone.Get the book or Get a Sneak Peek (PDF)
