"Other Cahills might laugh at the Holts, but there's more to Hamilton than meets the eye. He's a computer whiz who can hack into your laptop faster than it takes him to knock you out with a well-aimed dodge ball. Hamilton has the potential to be a major force in the hunt for the 39 Clues, as long as his father, Eisenhower, doesn't stop him from reaching his full potential. Will Eisenhower let Hamilton form a risky alliance with a rival team? Can they really trust any family that doesn't wear matching tracksuits?"
