He painted a portrait of Sophie when they married and, despite the risk of losing the painting to the Germans, she hangs it on the wall. As the story progresses, the reader wonders if the artwork might enable Sophie to see Edouard again. Jump to contemporary London, where Liv resides in a glass house that her architect husband, David, designed. She cannot put his death several years ago behind her. Her strongest connection to him is the painting that he bought for her, entitled The Girl You Left Behind, hanging on her bedroom wall. When Liv learns that the painting might have been stolen and may not be rightfully hers, she cannot help but fight to keep it. She also finds herself delving into Sophie's life and is compelled to protect Sophie's memory. The situation is complicated by the fact that the lead investigator in the effort to return the painting to the artist's family is Paul, the man she's recently fallen in love with.

The Girl You Left Behind combines an intriguing backstory with Sophie's World War I tale and a contemporary romance with Liv and Paul. For readers who enjoy Maeve Binchy and Katie Fforde.
