One disaster was buried beneath the Gulf. One inheritance was erased in Australia. One hidden ship carries the evidence connecting them all.
The Mercer brothers follow three separate investigations spanning the Gulf Coast, Australia, and the Pacific Northwest, each discovery exposing another piece of a conspiracy protected for decades.
In Black Gold Secret, Luke dives into the wreckage of an offshore catastrophe. In The Lost Claim, Noah fights to restore a stolen claim. In The Iron Vault, Eli searches a secret-laden vessel for records powerful enough to rewrite history.
The Mercer Files Complete Trilogy collects Black Gold Secret, The Lost Claim, and The Iron Vault in one fast-paced volume of clean action-adventure suspense, dangerous recoveries, buried family secrets, and slow-burn romance.
Three brothers. Three investigations. One conspiracy.
Follow the complete Mercer Files conspiracy from the first discovery to the final release of the proof. Available November 3, 2026.
