The Perdido Valley War - Aaron Cummins

Some men go looking for gold. Others go looking for the truth.

A year after his brother vanished in the New Mexico desert, Yiannis Papadopoulos arrives in the isolated Perdido Valley-only to find a place where silence is currency, strangers aren't welcome, and every man is armed with a lie.

They say there's a lost mine buried in the badlands.
They say men have killed for it.
They say the desert keeps what it takes.

As Yiannis digs deeper, he finds more than rumors-abandoned camps, hidden bodies, and a valley on the brink of war. Two rival factions are closing in on the same prize, and both are willing to bury anyone who gets in their way... Including him.

In a land where the law is bought, the truth is buried, and survival comes at a cost, Yiannis must decide: How far will he go to bring his brother home?

A gritty, hardboiled western noir about obsession, brotherhood, and the kind of war that never really ends.
