Driftwood Books is an established used book store in Portland, Oregon, owned by an inquisitive Rosalie Evans. Among the books she acquires for inventory at estate sales and auctions, Rosalie occasionally finds treasures such as vintage bookmarks, photos, letters, and even personal diaries. Believing that these diaries should have never been discarded, she is obsessed in finding clues to return them to the rightful families. The Driftwood Diaries contains three short stories that unveil three remarkable women. The Stone Lamp follows Marie, a young woman who has been thrust into a remote Alaskan archaeological site and discovers love and bravery in the face of seemingly overwhelming obstacles. Lonely Prairie is Susan Lee's story that begins with the American Civil War, follows her to Colorado, and describes her life as a mother and a rancher on the tall grass prairie of Texas, all the whole hiding a scandalous secret. In Valentines for Margaret, Rosalie Evans' own mother writes of her life as a child in the Great Depression of the Texas Panhandle.
