At eighty years old, Florence Carter is content with her life. A widow in her twilight years, she spends her days making intricate lino prints in the company of her dog and cat, and her neighbour’s daughter Alice, a shy young woman troubled by a recent trauma. But when ​Flo learns that a long-lost friend has written a novel based on their time at finishing school, she’s forced to confront a secret from her past...

In post-war Lyon, Florence and Lilli meet at a strict finishing school for girls. Florence—or Flo as she’s known—is a demure young Englishwoman who is expected to enter society and make a good marriage. Lilli, meanwhile, is a brash American with an independent spirit and thirst for adventure. Despite their differences, they forge a firm friendship that promises to last a lifetime—until a terrible betrayal tears them apart.

Now, as Flo reads Lilli’s book, she struggles to separate fact from fiction. Desperate for answers, she decides to take a road trip to France to find Lilli, and she invites Alice and her mother Carla to join her, in hopes the change of scenery will lift their spirits. But when they reach Lyon, it’s Flo who needs help as the buried truth from long ago threatens to overwhelm her.

The Lost Chapter is a poignant novel about the power of friendship and a beautiful reminder that it’s never too late to start writing a different story.
