Traitor in the Shipyard review

Andrew, my littlest brother, got me this book with his reading club form. (Can you say AWWW?) This is probably one of the best AG mysteries. It keeps you guessing until the very end.

• The American Girl: Caroline Abbot, from Sackets Harbor, New York.
• The plot: It's 1812, and Caroline's father's shipyard is frantically building ships to keep up with the British. When Papa's old friend arrives penniless, it's the least the the Abbots can do to give him a job. After all, he helped Papa escape from a British prison! Life is beginning to look up for Caroline. She even has time for sewing lessons at Miss Lucy's. But when things go missing around the shipyard, sails are slashed, and fires are started, Caroline soon realizes there's a British spy afoot- and it's someone who knows the shipyard well. Is it one of Abbott's trusted workers, whom she has known all her life, or could it be Papa's dear friend? It's up to Caroline to discover what's really going on.
• What I especially liked: Just when all the evidence pointed to a character you were SO sure was the spy, new clues and hidden pasts would come to light.  I loved that the plot wasn't easily guessable or boring. I also always enjoy the 'looking back' section, which told all about real-life spies in the War of 1812.

This was a very enjoyable and interesting  read, although I finished it quite quickly. It would be perfect for  ages 9-12, and was packed with facts about the war of 1812, which is an often overlooked part of our country's history.
