Forever Summer begins in the present as Kathryn visits the homestead farm that has been in her family for generations. The first night she finds an old journal and discovers that it was written almost one hundred years ago by a girl named Katie. The pages of the daily dairy transport her back to the farm as it was in the early 1900's. She actually becomes Katie, and life on the farm becomes her reality as it explores food, chores, holidays, and relationships of daily life. Many of the author's own experiences have been woven into this enchanting tale of two girls living in very different worlds.
