For six years, Wren Carter has lived quietly in the shadow of her superstar husband, Jace, secretly writing the songs that built his career while raising their twins alone. Wren finally walks away. What no one knows is that Wren is actually Wren Sinclair—the sole heir to a $40-billion entertainment empire—and the mysterious hit songwriter “Songbird” behind Jace’s eleven No. 1 songs. Once she stops writing for him and returns to her powerful family, Jace’s career begins to collapse, Sienna’s lies unravel, and the woman they dismissed as “nothing” finally reclaims her identity, her children, and her place at the top of the music industry.
