by Rick Riordan
Amy and Dan Cahill are orphaned kids who love their Grandma Grace. On the day of her funeral they are not just sad, they are stunned. She left a video for the Cahills and a whole bunch of evil distant cousins. It says that they are all part of the most powerful family in history and that they must choose between a million dollar check or a scavenger hunt around the world to find an object that will change history. What would you choose? Amy and Dan decide to take the challenge and are swept into a whirlwind of danger, puzzles and dastardly characters. This is the first in a series of books that will follow the scavenger hunt. There are clues in the book so you can play along.
