Learn the history. Solve the puzzles. Uncover the secrets of the seven!


When Sam Solomon entered the American Dream Contest, he did it for the puzzles—and the glory, of course. But what he didn't know was that winning that contest would get him a one-way ticket to the adventure of a lifetime! Along with history whiz—and card-carrying nerd—Martina Wright, Sam learns that they have been chosen for a very important mission, one that holds the safety of the entire United States in the balance! Together with strong, silent Theo and Evangeline Temple, their mysterious benefactor, Sam and Martina must journey cross-country on the trail of clues left behind by our nation's founding fathers. Skirting dangerous traps, solving puzzles, and digging deep into American history, the heroes need to outrun and outsmart the cunning Gideon Arnold at every turn—a villain who aims to use the Founders' secret for his own evil purposes. Will Sam and his friends solve the secrets of the seven, before it's too late?
