In 1937, seventeen-year-old Ellaâ€™s life changes forever when she is sent to spend the summer on the beautiful ÃŽle de RÃ© and meets the charismatic, creative Christophe. They spend the summer together, exploring the islandâ€™s sandy beaches and crystal-clear waters, and, for the first time in her life, Ella feels truly free.
But the outbreak of war casts everything in a new light. Ella is forced to return to Scotland, where she volunteers for the war effort alongside the dashing Angus. In this new world, Ella feels herself drifting further and further from who she was on the ÃŽle de RÃ©. Can she ever find her way back? And does she want to?
