At 28, Xenia Hewitt is diagnosed with early-onset Alzheimer's. To spare her husband, Tom, the pain of her decline, she vanishes. Six years later, Tom has become a powerful CEO, and Xenia is a shadow of her former self, her memories of him fading. When fate unexpectedly reunites them, he is a stranger she feels she knows, and she is the love he never forgot. Their reunion forces a heart-wrenching question: is rekindling a love that cannot remember itself a salvation, or the ultimate torment?
