When Riley discovers through a casual Instagram scroll that her divorced parents secretly remarried six months ago—without telling her—she's forced to confront the family dynamics that left her on the outside looking in. While her siblings were toasting in Santorini, she was living her life completely unaware that her family had been rewritten without her. Now back in their orbit for the first time since the wedding she wasn't invited to, Riley must navigate champagne-soaked family dinners, forced smiles, and the devastating question that keeps her up at night: why wasn't she enough to include? As long-buried secrets surface and allegiances shift, Riley learns that some family bonds can be rebuilt—and others were never as solid as they seemed. A sharp, emotionally resonant novel about belonging, forgiveness, and discovering that sometimes being left out is the push you need to finally find yourself.
