Springtime means that Felicity's birthday is coming. This year, springtime also brings a visit from Grandfather, who has a precious gift for Felicity -- a guitar that belonged to her grandmother. Felicity is so enchanted with the guitar that she disobeys her mother by taking it out of the house to show her friend Elizabeth and Elizabeth's sister Annabelle. Her parents and grandfather 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 more of her parents' anger when she decides she must alert the colonists herself!
