Lily St. Claire is not the kind to seek solace at the shorelines, yet a surprise inheritance from her late father leads her to a remote bungalow on Florida's Gulf Coast, the Hideaway Key. Expecting a simple cottage, she instead uncovers a trove of family history through a carton of old journals that once belonged to her estranged aunt, a woman whose very name is forbidden in the St. Claire household. As Lily delves into the pages, she unravels the enigmatic past of her family, uncovering truths that paint a different picture of her mother and her aunt as young girls from Tennessee. Through the revelations, Lily not only confronts her family's hidden stories but also embarks on a personal quest, stumbling upon potential love and pondering if she can ever open herself to trust again. As the secrets of the St. Claire family come to light, Lily is faced with the decision to either close the book on the past or allow these newfound understandings to guide her in forging a new path for her heart.
