Winner—Literary Titan Gold Book Award

Finalist—BestThrillers.com Book Awards

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

His debut novel earned the 2025 PenCraft Award for Best Thriller.

When historian Jack Sullivan, Smithsonian curator Emma Wilson, and former Navy SEAL Steve Johnson set out for a Thanksgiving dive off Cozumel, they expect warm waters and forgotten wrecks.

Instead, they discover a Confederate ghost ship that vanished in 1865—along with a secret powerful enough to rewrite history.

But they aren’t alone. A black-hulled yacht shadows their every dive. Mercenaries close in from the deep. And someone is willing to kill to keep the past buried.

From brilliant Caribbean reefs to the back alleys of Veracruz, Jack and his team are thrust into a deadly game where history isn’t past—it’s a weapon.

Some secrets want to be found. And some will kill to stay hidden.
