Annie Dawson's discovery of a diary in the attic of Grey Gables has set her on a mission. The diary reveals a poignant love story from World War II, a story cut short when young Peter Lambert goes off to the European Theater, leaving his young girlfriend, Lilly Pryce, with a promise: He will come back to her. But that promise is smashed when Peter's mother receives notice from the War Department that Peter is missing and presumed dead while on a mission behind enemy lines. Lilly's diary brings into focus Annie's personal tragedy -- and her growing relationship with Ian Butler, Stony Point's handsome mayor. Did Lilly find a new love after her loss of Peter? She is also intrigued by the discovery of several V-mail letters from Peter to Lilly and several photographs. Annie wonders: Whatever happened to Lilly after Peter's death? Where is she now? How did such personal belongings end up in her grandmother's attic? With the help of her best friend, Alice MacFarlane, and the other members of the Hook and Needle Club, Annie sets out to find the answers to this latest mystery. Along the way, they may also find the answer to that age-old dilemma: Can love once lost become love found again?
