A librarian inherits a bookshop from her estranged mother, leading her halfway across the world on a journey of self-discovery that transcends time and honors the unbreakable bonds of love and family.

When librarian Valentina Baker was a teenager, her mother, Eloise, unexpectedly fled to her native London, leaving Val and her father on their own. Now in her thirties and fresh out of a failed marriage, Val feels a nagging disenchantment with her life--and knows she is still heartbroken over her mother's abandonment.

In a bittersweet twist of fate, Val receives word that Eloise has passed away, leaving Val her Primrose Hill apartment and the deed to a bookshop Val never knew she'd owned. Though the news is devastating, Val finds herself more determined than ever to discover who her mother truly was. She jets across the Atlantic, departing Seattle for a new life in charming London.

Slowly but surely, Val begins to piece together Eloise's life in the UK, falling in love with her pastel-colored flat, cozy neighborhood, and tucked-away storefront. But when she discovers that The Book Garden is in danger of going under, Val must work with its eccentric staff to get it in working order. In the process, she learns more about Eloise than she ever thought possible. And as Val races to save the shop, Eloise's own story unfolds, leading both mother and daughter to unearth revelatory truths.
