Brilliant middle schoolers Sam, Martina, and Theo embark on another adventure (The Eureka Key), this time to find Jefferson's quill (the second of seven artifacts left by the Founding Fathers) in Montana. Numerous traps set by a descendant of Benedict Arnold are thwarted with the trio's puzzle-solving intelligence. Formulaic but fast-paced, with intrigue, interactive puzzles, and historical trivia for fans of the National Treasure movie franchise.
