Bronwyn stunned the world with a book written in an invented language that became a national sensation when she was just twelve years old.

As the headlines focus on the missing author, Clara yearns for something far deeper and more insatiable: her beloved mother. By 1952, Clara is an illustrator raising her own daughter, Wynnie. When a stranger named Charlie Jameson contacts her from London claiming to have discovered a handwritten dictionary of her mother's lost language. Clara is skeptical. Compelled by the tragedy of her mother's disappearance, she crosses the Atlantic with Wynnie only to arrive during one of London's most deadly natural disasters--the Great Smog. With asthmatic Wynnie in peril, they escape the city with Charlie and find refuge in the Jameson's family retreat nestled in the Lake District. It is there that Clara must find the courage to uncover the truth about her mother and the story she left behind."Graceful in its telling and so very wise in its insights, The Story She Left Behind is a book that will capture your heart, lift your spirits, and delight your soul" (William Kent Krueger, New York Times bestselling author).
