"For as long as anyone can remember, it's been Amy, Jo, and Ryan. Amy and Jo, the inseparable Sharp twins, who couldn't be more different. Amy and Ryan, the high-school sweethearts turned husband and wife, who have the next ten years planned out perfectly. Together through high school, college, weddings, there's nothing that could tear the three of them apart. While it's become harder for the group to spend as much time together, with life only getting more complicated with age, they always make it a priority to reunite every summer at the Sharp family home in Kismet on Fire Island, where they've been vacationing since they were children. But as this year's 4th of July weekend approaches, something feels off. Jo's whirlwind engagement and wedding ceremony now eclipse the twins' long-awaited 30th birthday. Recent arguments with Ryan have left their marriage feeling more like make-believe than ever-after. And as the family beach town transforms into "Jo's Wedding Weekend," Amy's trusted trio will be tested by the most unexpected hurdle yet: the arrival of a handsome, mysterious newcomer in a Best Man suit. One with a strikingly familiar face. One that Amy had planned to never see again. As Amy finds herself balancing the ghosts of her past with the heartache of her present, she'll be forced to confront her worst doubts: what if her fastidiously planned life hasn't been her destiny all along? And what if the people Amy loves the most have been the very same things standing in her way? This holiday weekend, even the strongest SPF won't protect the Sharp twins from all the secrets about to take center stage"-- Provided by publisher.
