Harriet Wolf's Seventh Book of Wonders tells the moving story of the unforgettable Wolf women in four distinct voices: the mysterious Harriet, who, until now, has never revealed the secrets of her past; her fiery, overprotective daughter Eleanor; and her two grown granddaughters -- Tilton, the fragile yet exuberant younger sister who's become a housebound hermit, and Ruth, the older sister who ran away at sixteen and never looked back. When Eleanor is hospitalized, Ruth decides it's time to do right by a pact she made with Tilton long ago: to return home and save her sister.
