Blood may be thicker than water, but guilt is heavier than both.

Lillian and her twin sister have never seen eye to eye, but when their father dies and a cryptic thumb drive is discovered in his study, old wounds are ripped wide open. Lillian begins to unravel the truth about their family's past—starting with the day their mother died, a day Lillian can't remember but has always felt guilty about.

As she listens to her father's private confessions, memories long buried begin to surface, forcing Lillian to question everything she thought she knew. The once-grand Alexander estate on Charleston's East Battery is crumbling, the family fortune is gone, and the sisters' fragile bond is strained to the breaking point.

With her inheritance slipping away and secrets rising like ivy on the walls of their historic home, Lillian must face the truth—or risk losing everything, including the sister she never stopped loving.
