My Sister’s Secret by Tracy Buchanan

Willow’s memories of her parents are filled with love and happiness, but her time with them was brief. A tragedy at sea took them from her when she was just a little girl, leaving Willow to be raised by her mother’s sister, Hope. Years later, she is back at her parent’s home, preparing it for sale, when she discovers an invitation for a photography exhibit—addressed to her, sent by a man she’d never met—opened and discarded in the trash. Willow questions her aunt about it, but Hope refuses to answer her questions. Frustrated, Willow searches for answers and, after discovering secrets that have been buried for years, wonders if her entire life has been built on a foundation of lies.
