Jojo Moyes's 'The Girl You Left Behind' masterfully weaves two compelling narratives across a century. In occupied France during WWI, Sophie Lefevre desperately tries to protect her family and a portrait painted by her artist husband, Édouard, from the Germans. Nearly a century later in London, Liv Halston inherits the same painting, unaware of its profound history. When the artwork's true value and controversial past are revealed, Liv fights to retain a piece of art that has become deeply personal. The novel beautifully explores themes of love, loss, memory, resilience, and the enduring power of art across generations, highlighting the sacrifices made for love and the legacies left behind.
