Smooth-talking, refined twelve-year-old Addison Cooke loves a grand adventure, especially one that involves using his vast knowledge of history and archaeology, learned from his aunt and uncle, both world-famous researchers. If that adventure includes an expertly-knotted Windsor tie and an Arnold Palmer on the rocks, all the better.

Luckily for Addison, adventure has a way of finding the Cookes. After Addison's uncle unearths the first ancient Incan clue needed to find a vast trove of lost treasure, he is kidnapped by members of a shadowy organization intent on stealing the riches. An expert in Incan history, Addison's uncle is the bandits' key to deciphering the ancient clues and looting the treasure. . . unless Addison and his friends can outsmart the kidnappers and decipher the clues first. So it's off to Peru (business class, no less), across the Amazon, and all the way to Machu Picchu in a race for riches and history.
