The graphic novel adaptation of the mega-bestseller that launched a
global phenomenon!
Minutes before she died Grace Cahill changed her will, leaving her
decendants 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 Marie Curie to Harry Houdini is related to the
Cahills, yet the source of the family power is lost. 39 Clues hidden
around the world will reveal the family's secret, but no one has been
able to assemble them. 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.
