"One of my favorite writers . . . It's about friendship, it's about life, it's about how people change . . . I loved it very much."—Marian Keyes

A heartfelt, funny, yet deliciously spicy enemies-to-lovers romcom set during a long summer weekend at an exquisite British seaside resort, centered around a group of old friends whose lives are about to change forever.

Sometimes all it takes is one long summer weekend for the person you thought you hated to become something more . . .

After a disastrous first meeting, Cassie and Marc are instant archnemeses. Despite Marc's frustratingly sharp cheekbones and sexy French accent—and the fact that Cassie's best friends Lucy and Russell think he's wonderful—Cassie is convinced that Marc's a terrible person who did a terrible thing, full stop.

But, years later, when their friends are hit with bad news, Cassie and Marc decide to put aside their differences and give Lucy and Russell the best weekend ever. While they can't change the past, they can help their friends make new memories with all of their favorite people. Which means convincing everyone that Cassie and Marc are head over heels in love, since their best friends have always thought they would be perfect together, and badly wish each would find an ideal partner.

After years of loathing Marc, it only takes four bittersweet days for Cassie to reconsider whether she got the man completely wrong all these years. But can the two let go of their troubled past, and together, face whatever the future will throw at them? Or is this doomed to be just another steamy vacation fling, never again to be acknowledged or repeated?
