A standalone thriller. New readers can start right here.
When Professor Jack Sullivan is asked to decode a cipher from the war’s final
days, he expects a historical curiosity. Instead, he uncovers a thread
Jefferson Davis died protecting, a secret never meant to resurface.
Jack, his fiancée Emma Wilson, and former SEAL Steve Johnson are pulled
into a hunt more dangerous than any battlefield. From Washington’s archives to
the back alleys of New Orleans, from the coast of Mexico to the shadowed
ridges of Arkansas, every trail leads deeper into the world of the Knights of
the Golden Circle, a brotherhood long believed defunct.
But the Knights didn’t disappear. They became patient.
For 160 years they studied what force could never win. They embedded
themselves in the institutions Americans trust, and waited for the moment when
they wouldn’t need to seize power. They would be invited to take it.
Now their heirs have risen. A cartel is running weapons north while a
cyberattack probes the power grid, and a senator climbs toward power on the
fear both create. Jack begins to realize he was never hunting the treasure. He
was being led to it.
Joined by Homeland cyber analyst Priya Patel and hunted by enemies he cannot
see, Jack has four days to break a design older than anyone imagined before
the trap closes around everyone he loves.
“The high-stakes, of-the-moment, infiltrated-America suspense simply does not
let up.”Â
— BookLife by Publishers Weekly
Some secrets don’t stay buried. They grow roots.
Great for fans of Steve Berry and Clive Cussler.
Praise for Echoes of Fortune: Knights of the Golden Circle
“One part Jack Reacher, one part Indiana Jones… an impressively entertaining
action thriller.”
— Kirkus Reviews (“GET IT”)
“Leng lets history press against the present, sometimes like a warning and
sometimes like a buried fuse.” — Literary Titan
About the Author
 David R Leng is the award-winning author of the Echoes of Fortune historical
conspiracy thriller series, winner of three PenCraft Awards, including
Thriller of the Year and back-to-back Best Thriller honors, two Literary Titan
Gold Awards, and a Kirkus Reviews “GET IT” selection.
A lifelong resident of Southwestern Pennsylvania, David grew up in the shadow
of the same battlefields his characters explore. He spent summers near the
Shades of Death wilderness in western Maryland and has kayaked the
Youghiogheny River, where a chance encounter with a stranger carrying a metal
detector and asking about Braddock’s gold planted the seed for the series.
His debut novel, The Search for Braddock’s Lost Gold, follows historian Jack
Sullivan into the unsolved mystery of General Braddock’s vanished army payroll
from the 1755 Battle of the Monongahela. The series has since expanded to the
sunken Confederate secrets of Cozumel and the shadowed world of the Knights of
the Golden Circle.
When he is not unraveling centuries-old conspiracies, David can be found scuba
diving, boating, or in his woodshop. He lives in Pennsylvania with his wife
and family.
