A forgotten book. A hidden ledger. A murder that refuses to stay buried.

When Clara Henderson receives a rare nineteenth-century history book for her beloved bookshop, Gossamer Fables, she believes she’s adding another treasure to her shelves. Instead, she discovers a concealed message hidden inside its repaired spine—one that points to a secret someone has protected for generations.

Before Clara can uncover the truth, the book’s former owner is found dead.

Together with innkeeper Amelia Farnsworth and Lady Grey—the remarkably intuitive British Shorthair who always seems to know where the next clue is hiding—Clara follows a trail of cryptic symbols, forgotten maps, and long-buried town records that lead to an abandoned lighthouse overlooking Tumblebrook Lake.

What begins as a search for the past soon becomes a race to uncover the truth before another life is lost.

As the mystery deepens, Amelia and Clara discover that Tumblebrook’s founders left behind more than stories. Hidden beneath decades of history lies a legacy powerful enough to change everything the town believes about itself—and someone is willing to kill to keep those secrets hidden.

Set along Minnesota’s breathtaking North Shore, The Bookseller’s Secret is a charming cozy mystery filled with unforgettable characters, a picturesque small town, an independent bookshop, loyal friendships, gentle humor, a clever cat, and twists that will keep you turning pages late into the night.
