The book is written in the form of a journal kept by Catherine Hall, a young girl living in a rural village in New England with her widower father and younger sister. The journal details her daily life between the years of 1830 and 1832. Among the events of these two years are several that would have a profound impact on the rest of her life. These include her assistance to an escaped slave, her father's remarriage, and the sudden death of her best friend.
