In the sun-drenched, class-divided world of the Outer Banks, where Pogues scrape by and Kooks live in luxury, twin brothers JJ and Juniper Maybank navigate a life of waves, trouble, and the silence of Juniper's world. Juniper, deaf since birth, relies on his sharp observations and the unwavering bond with his loud, chaotic twin. Their lives, a precarious balance of petty crime and loyalty, are thrown into disarray when JJ's best friend, John B, embarks on a dangerous search for sunken treasure. Suddenly, the quiet life Juniper knew is shattered by kook violence, police chases, and the thrilling, terrifying prospect of a treasure hunt that could change everything, or cost them their lives.
