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.

The sequel to the USA Today bestseller Silent Horizons, Riptide is an exhilarating, ripped-from-the-headlines thriller that blurs the line between duty and revenge―and leaves no one above suspicion.

Praise

"Riptide by Chad Robichaux with Jack Stewart is a sensationally propulsive and action-packed conspiracy thriller that brims with authenticity. Readers of Brad Thor, Tom Clancy, and Vince Flynn will be riveted by the new exploits of Foster Quinn."
- Mark Greaney, #1 New York Times bestselling author of the Gray Man series

"Riptide his hard―a relentless thriller about loss, betrayal, patriotism, and faith. The details make readers feel like insiders and the action sequences keep the pages flying. Thriller fans be warned: don't miss this one! "
- Kyle Mills, New York Times bestselling author of Fade In

"Explosive, authentic, and deeply human―Riptide isn't just a pulse-pounding thriller, it's spiritual warfare at its most gripping; a story that forces us to ask: when everything is taken from you, will you fight for justice... or surrender to revenge?"
- Andrews & Wilson, New York Times bestselling authors of the Tier One series and Tom Clancy's Act of Defiance and Defense Protocol

"With blistering action, razor-sharp detail, and a storyline that feels all too real, Riptide is everything I want in a thriller. Robichaux and Stewart balance heart-pounding suspense with the raw emotion of loyalty and betrayal, making this a powerful follow-up to Silent Horizons that hits even harder."
- Simon Gervais, former RCMP counterterrorism officer and bestselling author of The Elias Network

"Riptide pulls back the curtain on the war being raged on the inside that no one can see: the trauma, the anger, and the seductive pull of vengeance that can consume a soul. But it's also a reminder that redemption is real―that even in the darkest and deepest waters, God's grace reaches deeper still."
- Joby Martin, Lead Pastor of The Church of Eleven22 and bestselling author of Stand Firm & Act Like Men

"You want to know why Riptide reads so much better and more tactically realistic from other books of the same genre? Because it was written by a legitimate real-world operator, Chad Robichaux, and TOPGUN aviator, Jack Stewart."
- Nick Freitas, Former US Army Special Forces 

"Chad Robichaux is a master storyteller. He and Jack Stewart had me hooked by the first page and choked up at the closing line of the prologue. This captivating story is more than just entertaining―it explores the deep tension between fighting from virtuous principles or feral emotion. Conflict finds us all. The foundation we choose to fight from matters as it determines the end-state by defining what victory looks like. Some things are worth fighting for, no matter how high the cost."
- Bradley Geary, Captain USN (retired) Navy SEAL, author, and public speaker
