Fourteen-year-old Amy Cahill and her younger brother, Dan, have had enough. Not only do they have to find the 39 Clues first, they're expected to reunite their backstabbing family - the same people who killed their parents. But Amy and Dan haven't survived explosions and assassination attempts for nothing. They have a plan to finish the Clue hutn on their own terms. Too bad there's a final, fatal secret the Madrigals haven't told them. A secret that could cost Amy and Dan - and the world - everything.
