Feeling lonely and out of place after her family moves to a new town, eleven-year-old Fiona Crane ventures to the local library, where she finds a gripping mystery novel about a small town, family secrets, and a tragic disappearance. Soon Fiona begins to notice strange similarities that blur the lines between the novel and her new town. With a little help from a few odd Lost Lake locals, Fiona uncovers the book's strange history. Lost Lake is a town of restless spirits, and Fiona will learn that both help and danger come from unexpected places--maybe even from the sister she thinks doesn't care about her anymore.
