Though her mind is still sharp, Elizabeth's bones have aged and her eyes have failed. No longer able to linger over her beloved books or gaze at the paintings that move her spirit, she fills her days at the retirement home with music and with memories of her family, especially of her beloved twin sister, Emily. When her late father's journals are discovered after a tragic accident, she seizes the opportunity to piece together the mysteries of her childhood. With the help of Morgan, a delinquent teenager performing community service at the home, Elizabeth delves into the diaries--a journey through time that brings the two women closer together. Each entry draws these unlikely friends deep into a world far removed--to Porphyry Island on Lake Superior, where Elizabeth's father served as lighthouse keeper and raised his young family in the years before and during World War II. As a complex web of secrets unravels, Elizabeth and Morgan realize that their fates are connected to each other and to the isolated island in ways that are at once heartbreaking and healing. Both sweeping and intimate, The Lightkeeper's Daughters takes readers on an enthralling journey to an unforgettable place.-- Provided by publisher.
