This summer, will three weekends in a Fire Island share house be enough time for Maggie Monroe to fix her life, find love, and make sure she doesn’t lose her friends for good?

It’s been six years since Maggie followed her screenwriting dreams to Los Angeles and forgot to look back. But things in Hollywood didn’t go quite to plan. Now, twenty-five and suddenly home in New York, Maggie doesn’t know who she’s more anxious to see: her ex-boyfriend, Mac, or her ex–best friend, Liz.

For Liz, Maggie is the girl who abandoned her at the worst possible moment and an unwelcome surprise who could derail her perfect summer. Liz is recently engaged to her high school sweetheart, Cam, but Maggie’s arrival brings old wounds bubbling to the surface, exposing the cracks in Liz’s apparent happily ever after.

When Maggie accepts her former friends' unexpected invitation to join in their summer share house, a rental named Serendipity, she knows it’s the chance she needs to get her life back on track. For three weekends, Maggie, Liz, Cam, Mac, and their closest friends will take the ferry to Ocean Beach, Fire Island, for some sun-kissed bliss, if only they can avoid the drama of their past catching up to the present.

With the nostalgic flavor of a stack of sepia-toned Polaroids, and perfect for fans of Emily Henry, Jennifer Weiner, and Ann Brashares, this big-hearted, page-turning story delves deep into a complicated friend group as they navigate one messy yet magical midtwenties summer.
