Description
By: Rick Riordan | Illustrator: Ethan Young | Age: 8+
Minutes before she died Grace Cahill changed her will, leaving
her descendants an impossible decision:
"You have a choice - one million dollars or a clue."
Grace is the last matriarch of the Cahills, the world's most powerful
family. Everyone from Napoleon to Houdini is related to the
Cahills, yet the source of the family power is lost. Now the clues
race is on, and young Amy and Dan must decide what's important:
hunting clues or uncovering what REALLY happened to their parents.
