Answering a woman’s desperate call for help, young Navy widow Helen Devries opens her Whidbey Island home as a refuge to Choi Eunhee. As they bond over common losses and a delicate, potentially devastating secret, their friendship spans the remainder of their lives.

After losing her mother, Cassidy Quinn spent her childhood summers with her gran, Helen, at her farmhouse. Nourished by her grandmother’s love and encouragement, Cassidy discovers a passion that she hopes will bloom into a career. But after Helen passes, Cassidy learns that her home and garden have fallen into serious disrepair. Worse, a looming tax debt threatens her inheritance. Facing the loss of her legacy and in need of allies and ideas, Cassidy reaches out to Nick, her former love, despite the complicated emotions brought by having him back in her life.

Cassidy inherits not only the family home but a task, spoken with her grandmother’s final breaths: ask Grace Kim—Eunhee’s granddaughter—to help sort through the contents of the locked hope chest in the attic. As she and Grace dig into the past, they unearth their grandmothers’ long-held secret and more. Each startling revelation reshapes their understanding of their grandmothers and ultimately inspires the courage to take risks and make changes to own their lives.

Set in both modern-day and midcentury Whidbey Island, Washington, this dual-narrative story of four women—grandmothers and granddaughters—intertwines across generations to explore the secrets we keep, the love we pass down, and the heirlooms we inherit from a well-lived life.
