Sought-after social media influencer Sara Vance, in recovery for a serious health disorder, is coming into her own, with a potential career expansion on the horizon. Despite the good news, her successful siblings (and their perfect spouses) have a way of making her feel like the odd one out. So, when her unreliable boyfriend is a no-show for a Florida family vacation, Sara recruits Luis Navarro—a gorgeous firefighter paramedic and dive captain willing to play the part of her smitten fiancé . . .

Luis’s big Cuban familia has been in Key West for generations, and his quiet strength feeds off the island’s laidback style. Though guarded after a deep betrayal, he’ll always help someone in need—especially a spunky beauty with a surprising knowledge of Spanish curse words. Soon, he and Sara have memorized their “how we met” story and are immersed in family dinners, bike tours, private snorkeling trips . . . sharing secrets, and slow, melting kisses. But when it’s time for Sara to return home, will their island romance last or fade with the stunning sunset?
