A treasure hunter and the bestselling adventure novelist who broke her heart after one successful expedition reunite for a summer to search for lost riches.

Treasure hunter Stella Moore dreams of having it all—wealth, love, and a flourishing career—but knows she’ll never be that lucky. Every summer she and her childhood friends travel to search for hidden treasure, but she can barely manage her bills, let alone a relationship. Then, a chance encounter with alluring novelist Huck Sullivan during an expedition in Iceland has Stella thinking maybe her fortune has changed.

After his last book bombed, Huck hasn’t written a word. Joining Stella and her crew on an adventure seems like the perfect distraction from his problems, and when the crew finally uncovers hidden treasure, he is certain that he’s found more than just inspiration for his next novel. Huck and Stella’s undeniable connection gives way to an unforgettable night on a black sand beach.

After Huck disappears without a goodbye, Stella vows to put the heartbreak behind her—but that’s easier said than done when, a year later, every bookstore has a life-size cutout of her ex-lover next to stacks of his latest record-breaking bestseller. Good thing it’s time for another summer treasure hunt. Stella throws herself into mapping the path to a shipwreck off Key West, but the last thing she expects is an extra crew member showing up in search of material for a sequel and a second chance.

Stella and Huck are prepared for storms, sharks, sea sickness, even a tentative truce. But facing the feelings they buried and confronting the devastating truth about why Huck left is the only way to find what their hearts have been searching for all along.
