The Sapphire Signet

The attic held secrets, and three girls in a quiet house were just bored enough to find them. When Nan, Betty, and their tomboy cousin Bob stumble upon a leather-bound notebook hidden behind loose bricks, they discover something far more intriguing than dusty relics: a cipher, a map, and a trail of words pointing to buried treasure. But this isn't ordinary plunder. The treasure belongs to a loyalist family who fled during the American Revolution, leaving behind a fortune in silver and a mystery that time nearly erased. As the girls crack the code and follow clues through old houses, foggy docks, and the stubborn memories of elderly locals, they realize the real prize isn't the silver at all. It's the story: a window into a pivotal moment in American history, seen through the eyes of people who lived it. The notebook belonged to a young girl, once, who trusted that someday someone would understand. This is old-fashioned adventure with real teeth: the kind where children solve problems through cleverness and courage, where the past isn't a lesson but a puzzle waiting to be touched.
