The third book in the Secrets of the Seven series offers the further harrowing exploits of three intrepid kids recruited by descendants of America's founding fathers. Now tracking down clues related to Alexander Hamilton, middle-schoolers Sam, Martina, and Theo creatively solve puzzles while attempting to outwit and outmaneuver ruthless villains seeking national treasures for their own nefarious purposes. Thomson achieves a good balance of history, mystery, comedy, and narrow escapes, while driving the continuing narrative forward. From diverse backgrounds, the three main characters become increasingly interesting as they reveal themselves more fully to their companions (and to readers) in each adventure.

Now in New York City, brainy middle-schoolers Sam, Theo, and Martina search for the third historical artifact hidden by a Founding Father. With Gideon Arnold (Benedict's descendant) and his goons still in hot pursuit, the kids race to crack ciphers, riddles, and American-history trivia questions--all related to Alexander Hamilton. It's the National Treasure formula yet again, but series fans likely won't mind.
