Lena Hart spent fourteen years fighting her way from Nashville dive bars to the Grammy stage. Then one diagnosis threatened to take away the only thing the world had ever valued her for—her voice. On the day she learns she has laryngeal cancer, Lena discovers her secretly married husband, record-label founder Adrian Cole, shopping with Sophie Lane, a twenty-one-year-old singer styled to look exactly like Lena did at the beginning of her career. But Sophie is more than a young artist Adrian wants to promote. She is Lena’s replacement. Adrian uses their hidden marriage to secure Sophie industry connections, accesses Lena’s private songwriting archive, and gives the young singer “Möbius”—the deeply personal anniversary song Lena wrote for him. Adrian believes one song will cost his wife nothing. He is about to discover how much power Lena still holds. While preparing for the fight of her life, Lena quietly secures her original recordings, hires an attorney, and begins uncovering what her husband and his company have taken from her. Then, on the night she reaches the highest point of her career, Lena leaves her seat empty, releases one final song, and disappears. Adrian once built an empire from her voice. Now Lena must decide what remains when the music stops—and whether the woman behind the songs can finally belong to herself.
