This historical novel for young adults details the horrors of the Philadelphia Yellow Fever epidemic in 1793 from the point of view of a fourteen-year-old, Mattie, who runs a coffeehouse with her widowed mother and grandfather. In the course of the story, her mother is taken ill, she herself falls ill on the way to the safety of the countryside, and her grandfather dies of heart failure after nursing her. Separated from her mother who is also removed from the city, Mattie finds herself scrabbling for survival in a mostly deserted town after the death of her grandfather, but relocates the free black woman, Eliza, who had worked for her family and who essentially becomes part of her family.
Eventually the mother returns, an invalid but alive, and Eliza and Mattie undertake to run the reopened coffeehouse together and care for Eliza's nephews and an orphaned child Mattie has rescued. Hope reappears with the first frost in the forms of a reopened farmers' market, the return of George Washington to the town, and the reappearance from enforced isolation of Nathaniel Benson, a young painter who gives Mattie a vision of a future life with friendship and love.
