Riptide

A shadow war rages. Only one man can drag it into the light.

Still haunted by his former teammate’s betrayal and the unveiling of a conspiracy that runs deeper than he imagined, Foster Quinn is once more thrust back into the world he thought he left behind. In the sweltering heat off the coast of Key West, a mission to seize a billionaire’s yacht ends in a chilling revelation: America’s enemies aren’t just beyond our borders―they might be sitting in Congress.

When a powerful Texas businessman recruits Foster to investigate the political malfeasance behind the death of his son, Foster is pulled into a web of corruption that leads him from a luxury megayacht in the Caribbean to a tech mogul’s grand estate in the Pacific Northwest. As he hunts down the men pulling the strings, Foster must resist the temptation in his search for justice to be swept away by revenge. He’ll need all his training and resilience to unravel a plot driven by greed and masked by patriotism. Especially when the war becomes personal, and he realizes it’s coming to his own turf.
