Celebrated romance author Catherine Swift has topped the bestseller lists for decades, though her personal story hasn't been quite so successful. Three failed marriages have left her relationship with her daughters strained, but that's about to be rectified. Engaged yet again, Catherine is counting on this wedding to be what finally brings them together as a family, and she'll do whatever it takes to make that happen.

Adeline doesn't know what's worse--that her mother is getting married a fourth time, or that she's being guilted into witnessing the train wreck at Catherine's luxury villa in Corfu. It brings back the pain of her parents' split, of her mother's infidelity and the baby that was the result. Not that she blames her half sister, Cassie, but then she's never made an effort to know her, either.

Cassie, on the other hand, is thrilled by her mother's news and admires Catherine's resilience. She's equally excited about meeting the mystery groom, and at the prospect of spending her summer in Corfu, where she can process a secret of her own she's been keeping from everyone.

As Cassie and Adeline arrive on the island, they each have very different expectations of what this week will bring--they haven't been entirely honest with their mother about their lives, either--but in the lead-up to the wedding, all will be revealed, for better or worse.
