About Jack Stewart
USA Today bestselling author and retired naval aviator, Jack Stewart brings over twenty years of real-world experience as a Navy FA-18 fighter pilot and veteran of the special operations community to the pages of his fast-paced military thrillers.
About 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.
