From back cover:
In 1775 the British invaded Philadelphia. Sally Wister, a 16 year old girl, was sent to the countryside to avoid harm. During her time there. . . she kept a journal. This lively diary has not been available to the book-buying public in nearly 100 yrs., but it is a vital and delightful record of a young girls' life during a perilous and all-important time in American history.
