This Song Is About Me by Melissa de la Cruz

It was a night to remember. Ryan Holding, the most famous pop star in the world, won every music award imaginable at the industry’s highest event. She exited the stage to thunderous applause…then disappeared off the face of the earth.
Six years later, her social media accounts remain untouched. Her band has broken up. Her Malibu estate sits quiet. And billions of obsessed fans still ask: Whatever happened to Ryan Holding?
Amid theories, suspicions, and rumors, reporter Elyse James wants the truth about the girl who poured her heart into every song she wrote. As Elyse searches through the stories of Ryan’s life, from those willing to talk—her best friend, a childhood teacher, and Ryan’s first love among them—a portrait of a flesh-and-blood icon begins to emerge. So do clues to a mystery that has captivated the world.
Did Ryan disappear to find herself? Or did someone deliberately make Ryan disappear? The answers are the stuff of legend.
