Rick Riordan

Janus Branch. It took Riordan years to work up the courage to write the first 39 Clues book. His experience writing the Percy Jackson and the Olympians series prepared him for The 39 Clues. Riordan and his family now live in hiding somewhere near San Antonio, Texas.

After their grandmother dies, Amy and Dan Cahill discover that they are part of the most powerful family in history. The source of this power is hidden in 39 Clues scattered around the world. Amy, Dan and other Cahills are given a choice: Take a million dollars and walk away, or compete to find all the Clues. The first Clue is somehow connected to Benjamin Franklin, but its location is a mystery.
