Olivia Grant inherits a small, struggling bookstore in Seattle and plans to sell it quickly to return to her fast-paced life in Chicago. While organizing the shop, she discovers mysterious handwritten notes tucked inside random books, each signed with only the initial “J,” that seem to speak directly to her heart. As Olivia tries to uncover the author of the notes, she forms a connection with Ethan, a quiet and thoughtful man who visits the shop daily. Together, they discover that love can be found in the quietest, most unexpected places, sometimes hidden between the pages.
