​"What happens when your 'once-in-a-lifetime' girl is actually the 'one-in-a-billion' pop star you're obsessed with?" Parker Green is a professional over-thinker and a dedicated archivist of things that don't belong to her. At twenty-eight, her life is a mess of dusty maps and a secret Twitter fan account for Athena-the world's most elusive, masked pop sensation. ​After a brutal breakup caused by her "unhealthy obsession" with a woman who wears a gold mask and never shows her forehead, Parker's friends give her an ultimatum: Get a real life, or lose your mind. ​Enter Nicole. She's stunning, she's mysterious, and she's sitting at Parker's favorite pub. For the first time in years, Parker feels a spark that has nothing to do with fan theories or music videos. But as their romance blooms, Parker has to hide her massive shrine to Athena to avoid looking like a total psycho. ​The only problem? Nicole has a mask of her own. A literal one. Because Nicole is Athena. ​In a world of secret identities, high-stakes fame, and embarrassing fan-girl moments, can a relationship survive when it's built on a lie? Or will the truth be the one thing that brings the curtains down?
