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?

Cassie Scott will do anything for her best friend, so planning a surprise milestone birthday weekend is an easy task—or it should be.
Author Sarra Manning serves up a fast-paced enemies-to-lovers story in The Last Days of Summer. The last person Cassie wants to work with is her nemesis, Marc Lacourt.
While they both share friendships with Lucy and Russell, they must set aside their differences. The author weaves in plenty of snarky comments as the two face off.
Underneath the jabs and insults, a heated connection lies dormant until one moment in the pantry. To save face upon discovery, Cassie deviates from the truth and reveals a relationship with Marc.
Over the course of four days, close proximity leads to new revelations. The pacing allows the story to unfold naturally without seeming rushed or contrived. The only question is whether their connection is built to last.
The Last Days of Summer highlights the power of friendship while allowing two people to navigate an unexpected attraction.
