Every summer, the Pembrokes and Beaumonts return to the private island their families have shared for generations. Between bonfires at Lantern Dock, late nights at Moonstone Cove, and traditions older than any of them, the island feels untouched by time. But this summer is different. Adelaide Pembroke and Oliver Beaumont are no longer children, and years of bickering, familiarity, and unspoken attention are becoming something neither can ignore. As old family tensions resurface and a decades-old rule forbidding relationships between the two families is challenged once again, the next generation begins questioning whether the past deserves to control their future. A coastal coming-of-age romance about family, first love, second chances, and the place that always brings them home.
