Some secrets are buried for a reason.

Eight years ago, Lizzie Legard's sister vanished from a Key West beach without a trace. Now home from college, Lizzie seizes the chance to join a treasure diving crew when her boyfriend is injured-but working alongside his brooding older brother, Damen Wisler, wasn't part of the plan.

Damen is everything Lizzie should avoid: a battle-hardened Navy SEAL with a dangerous reputation and zero interest in his family's treasure hunting legacy. He was there the day her sister disappeared, searching the waters that yielded nothing but heartbreak. The last thing he needs is to be captivated by his little brother's girl-especially when her wealthy family would never accept someone like him.

But beneath the turquoise waters of the Gulf, they discover more than Spanish gold. When shocking evidence surfaces about her sister's disappearance, Lizzie realizes the killer has been hiding in plain sight all along. As a deadly hurricane barrels toward the Keys, threatening to bury the truth forever, Lizzie must choose between the safety of silence and the dangerous pursuit of justice.

With betrayal lurking in every shadow and passion igniting between unlikely lovers, Lizzie and Damen race against time and tide. But in a town built on secrets, some treasures come with a deadly price-and the most dangerous catch of all might be falling in love.
