The Secret of the Silver Letters. The Silver Meridian Saga, #5

A vanished World War II ship. A hidden code written in silver. A discovery capable of exposing the truth behind the Sterling legacy. Leo Sterling returns to Tuscany for one reason only: to sell the family winery and leave the past behind. But hidden among forgotten barrels and sealed documents, he discovers a letter pointing toward the Santa Isadora-a ship that disappeared in 1943 carrying a secret powerful enough to alter history.
The wreck was never found. Until now. Joined by Sofia, a historian determined to uncover the truth, Leo follows a trail stretching from the Italian coast to dangerous international waters. But they are not the only ones searching. The Vortex Corporation believes the Santa Isadora carried one of the missing Silver Meridian artifacts-an object connected to a hidden global network buried for generations.
As alliances fracture and deadly storms gather at sea, Leo and Sofia realize the greatest danger is not what sank beneath the ocean. It is what survived. The Secret of the Silver Letters is a cinematic historical thriller filled with lost relics, wartime conspiracies, and dangerous family secrets.
