The Grave Creek Cipher (en Inglés) - Gideon Mercer

A dead digger. A sealed mound. A cipher hidden beneath the Ohio Valley.

After the horrors of Blennerhassett Island, Silas Coane thought he had escaped the broken-tower mark.

He was wrong.

When a warning arrives with a smear of dark clay and a strand of reddish hair, Silas follows the Ohio River north to Grave Creek-where an ancient mound has been opened in secret, and the first man to see what lay beneath it is already dead.

At Grave Creek, Silas finds Eliza Ward, a schoolteacher whose missing father copied records powerful men would rather burn than explain. Together they uncover a trail of false land deeds, dead men's signatures, river warehouses, church vaults, stolen artifacts, and a stone tablet whose missing center may unlock the mystery that began on Blennerhassett Island.

But Julian Voss is not the only man guarding the secret.

Behind him stands Elias Vale, a colder and older power tied to the split-circle symbol, hidden western surveys, and a relic system that reaches far beyond one mound. As evidence burns and bodies fall, Silas and Eliza must rescue what can still be saved before Grave Creek is sealed forever.

Because the mound is not merely a grave.

It is a lock.

And something west of the Ohio is waiting for the key.

The Grave Creek Cipher is Book 2 in The Ohio Valley Relics, a historical adventure mystery series filled with ancient American legends, buried artifacts, secret societies, red-haired giant lore, and dangerous men determined to control the past.
