Just before losing a battle with cancer, Suzanne Carter sent letters to childhood friends from her hometown of Sweethaven, Michigan. Suzanne's three friends -- Lila, Jane, and Meghan -- haven't spoken in years, yet each has pieces of a scrapbook they made together as girls. Suzanne's letters have lured them all back to the idyllic lakeside town, where they meet Campbell and begin to remember what was so special about their long Sweethaven summers. As the scrapbook reveals secrets from the past, old wounds are mended, lives are changed, and friendships are restored -- just as Suzanne intended.
