Always each other’s plus-ones, but never each other’s real dates, two childhood best friends have one last summer wedding to fall in love in this dual-narrative debut.

“Left me feeling desperately romantic. Prepare for a book hangover—I loved it.” —Annabel Monaghan, bestselling author of Summer Romance

Best friends Joni and Ren have been inseparable since childhood. So when Joni moves across the country for her job, the two devise a creative way to stay in touch: they’ll be each other’s plus-ones every year for wedding season, no matter what else is happening in their lives.

It’s a tradition that works, until a line is crossed and the friendship they once thought was forever is ruined.

Now Joni is back at their families’ shared summer home for her sister’s wedding, and she’s determined to make the week perfect, even if it means faking a friendship with Ren—and avoiding the truth of why they have to fake it in the first place. How hard can it be to pretend to be friends with the person who once knew you best?

But as sunny beach days together turn into starry nights, Joni begins to question what her life is without Ren in it. And when the wedding arrives, bringing past heartaches to the surface, she’ll be forced to decide if loving Ren means letting him go, or if theirs is a love story worth fighting for.
