About this item
Middle school geniuses Sam, Martina, and Theo arrive in New York City on a mission. They're after the third key left behind by the Founding Fathers. They've escaped the forests of Glacier National Park with the second key, but at great cost--Evangeline, their chaperone and friend, was captured by the nefarious and dangerous Gideon Arnold.
Now they have to navigate New York City following clues related to Alexander Hamilton, solve (and survive) the puzzles and traps they encounter along the way, and find the third key before Gideon Arnold does. But the stakes have never been higher, and they might not all make it out alive . . .
Another exciting adventure filled with clues, puzzles, and action that dives into the fascinating history behind the Founding Fathers and our country's natural wonders.
