Lizzy Munro is working at the Cannes Film Festival, in a job that involves a lot more admin than red-carpet glamour.
There, Ciaran Flynn is the man everyone is talking about: heartthrob of the moment and director of the most romantic movie of the year.
What nobody knows is that twelve years ago, they were best friends . . . and they haven't spoken since.
But when Ciaran's film runs into trouble, there's only one person he can turn to.
Is twelve days enough to save not only Ciaran's film, but also the spark he and Lizzy once shared?
