What would you risk to uncover a secret buried for over 150 years?

From bestselling and multi–award-winning author David R. Leng comes the next pulse-pounding installment in the Echoes of Fortune series.

His debut, Echoes of Fortune: The Search for Braddock’s Lost Gold, captivated readers and earned a 4.5-star rating on Goodreads. Now the adventure continues with a brand-new novella that plunges deeper into history’s deadliest secrets.

When historian Jack Sullivan, Smithsonian curator Emma Wilson, and fellow former Navy SEAL Steve Johnson set out for a Thanksgiving dive off Cozumel, they expect nothing more than warm waters and forgotten wrecks. Instead, they uncover a Confederate ghost ship that vanished in 1865—along with a sealed brass tube containing secrets powerful enough to change history.

But they’re not alone. Shadowy mercenaries and a black-hulled yacht stalk their every move, determined to silence them before the truth surfaces. From dazzling reefs to the back alleys of Veracruz, Jack and his team are forced into a deadly game where history isn’t past—it’s a weapon.

Some secrets don’t want to be found. And some will kill to stay buried.

Perfect for fans of Steve Berry, Clive Cussler, Dan Brown, and James Rollins, Shadows Over Cozumel delivers nonstop action, historical intrigue, and a mystery that spans centuries.
