Delia Greyson is looking forward to a quiet summer in her west coast beach town before heading off to Juilliard in the fall to pursue her musical passion. With miles of sandy beach beneath her feet, sunny days in the forecast, and having her twin sister Indigo and best friend Samson to keep her company between working shifts at the gift shop, it seems that the summer will be all smooth sailing. But things become unexpectedly rocky when her ex comes back to town for one last summer after breaking her heart the last. And he's not alone; with his new girlfriend in tow, Delia is left feeling cast adrift in her own hometown. With a bold plan hatched by her sister, Delia convinces Samson to play the role of adoring boyfriend. As feelings get complicated and the lines begin to blur in the fake relationship world, things get even messier when her estranged father and step family make an appearance for the first time. From catastrophic mini-golf dates to awkward family dinners, Delia struggles to not get caught in her own tricky web of lies. But everyone is not as they seem and everything is not as simple as it's made out to be. It's the summer of unforeseen firsts and long awaited lasts. It's the summer that changed it all, and the one that no one will forget.
