A COLE MACKEY THRILLER · BOOK ONE
GHOSTS OF THE BREACH
They killed his team. Six years later, someone killed the man who discovered why.
When Marcus Hale is murdered in Savannah, retired Navy SEAL Senior Chief Cole Mackey follows the clue his old teammate died protecting. It points back to a mission that went wrong six years earlier—and to someone powerful enough to keep the truth buried.
From a black site in Sudan to the shadows of Syria, Cole gathers the people he still trusts. But every step toward the truth puts them in the sights of an enemy who knows how they operate.
