Spring brings Felicity's 10th birthday on April 21, 1775 and a visit from Grandfather. He gives Felicity a precious gift—a guitar that had belonged to her grandmother.

Her parents are angry when they learn what she’s done. They refuse to believe a message Felicity has overheard that means danger for the colonists. Felicity risks her parents’ anger again when she decides to alert the colonists herself!
