When Annie finds a bundle of old letters in the attic of Grey Gables, she feels a rush of nostalgia for the days she spent in Stony Point as a child, and for her best childhood friend Susan Morris. Annie had saved these letters and brought them back to Stony Point to share with Susan, but where is Susan now? Annie's friends in the Hook and Needle Club have conflicting stories, but Susan is definitely not in Stony Point. Annie takes up the search for Susan, and as she digs deeper, she is drawn into a frightening game of hide and seek with strangers who threaten Annie's life and the lives of her friends--From publisher's description.
