When a burned-out pickup belonging to his murdered father is discovered high in the Wyoming mountains, Jake Mercer believes he's finally found the missing piece of the Caldera conspiracy.
Instead, he's opened the next file.
Hidden beyond Blackstone Pass lies a secret buried long before the first shot was fired in False Trail-a forgotten vault, a decades-old betrayal, and evidence proving the organization Jake thought he destroyed was only one branch of something far larger.
As bodies begin to surface and an invisible enemy known only as The Archivist manipulates every move from the shadows, Jake and Sheriff Emma Lawson race across snow-covered peaks, abandoned mining towns, and forgotten Cold War bunkers to uncover the truth before history is erased forever.
But the deeper Jake digs into his father's past, the more impossible the truth becomes.
What if Tom Mercer wasn't trying to destroy the conspiracy?
What if he helped build it?
Blackstone Pass is the explosive second novel in the High Country Files series-a relentless blend of Western grit, pulse-pounding action, and conspiracy thriller that will keep readers turning pages long into the night.
