When Solène Marchand, the thirty-nine-year-old owner of a prestigious art gallery in Los Angeles, takes her daughter, Isabelle, to meet her favorite boy band, she does so reluctantly and at her ex-husband's request. The last thing she expects is to make a connection with one of the members of the world-famous August Moon. But Hayes Campbell is clever, winning, confident, and posh, and the attraction is immediate. That he is all of twenty years old further complicates things.

What begins as a series of clandestine trysts quickly evolves into a passionate relationship. It is a journey that spans continents as Solène and Hayes navigate each other's disparate worlds: from stadium tours to international art fairs to secluded hideaways in Paris and Miami. And for Solène, it is as much a reclaiming of self, as it is a rediscovery of happiness and love. When their romance becomes a viral sensation, and both she and her daughter become the target of rabid fans and an insatiable media, Solène must face how her new status has impacted not only her life, but the lives of those closest to her.
