When Tia Dolores, the beloved aunt who has cared for the Montoya family since the death of their mother, announces that she is planning to leave, Josefina and her sisters try to find a way to change her mind.

When Elizabeth's sister, Annabelle, becomes engaged, Elizabeth and Felicity play pranks on her to tease her out of her silliness, but when their pranks backfire, Elizabeth and Felicity must find a way out of the trouble they've created.

Shortly before the Revolutionary War, nine-year-old Felicity, who lives in Williamsburg, is torn between supporting the tariff-induced tea boycott and saving her friendship with Elizabeth, a young loyalist from England.

As her tenth birthday approaches, Felicity is excited by her grandfather's visit, but she is also concerned about the growing tensions between the colonists and the British governor in Williamsburg.
