“Perfect for fans of Jack Carr’s Terminal List or Mark Greaney’s Gray Man series, Silent Horizons blends covert operations, geopolitical intrigue, and personal sacrifice into a riveting package.” — Ryan Steck, The Real Book Spy and Author of Gone Dark
Action fans are going to have fun with this one.
Drawing from their own elite backgrounds—Robichaux as a Force Recon Marine and Stewart as a Navy TOPGUN fighter pilot—the genre’s newest writing duo teams up for Silent Horizons, launching a gripping new military thriller series with explosive authenticity and heart-pounding suspense.
At the center of this exciting new series is Foster Quinn, a battle-hardened Marine who’s no stranger to danger, high-risk missions, or personal demons. But when he returns home to find that Robert James, one of his closest brothers-in-arms, has been killed, the pain cuts deeper than any wound he’s ever taken in the field. In a fog of emotions as he tries to readjust to civilian life, Quinn learns that James had been working to dismantle an international arms network, but ultimately has more questions than answers about his friend’s death. His quest for the truth, though, makes his personal life harder, and soon Quinn finds himself straddling two worlds as he struggles to juggle the responsibilities of home and the unshakable bond of military brotherhood.
Ultimately, it’s that loyalty that pulls him back into the fight.
Trying desperately to hold his fractured marriage together while still wrestling with grief, Quinn gets a rare second chance—an off-the-books mission in Iran that could bring his friend’s killers to justice and stop an arms pipeline in its tracks. It doesn’t take him long to accept the job; after all, war is what he knows best. This mission, however, is the most dangerous of his door-kicking career. Working under a cover identity, Quinn must quickly learn to navigate an unforgiving landscape of double agents, shifting allegiances, and ruthless enemies, all set against the backdrop of a foreign territory, in order to lay the groundwork for a top-secret operation that’s been in the works, but suddenly hinges all on him.
Alone and outnumbered, Foster Quinn must find a way to finish the mission his best friend started . . . but secrets await, and as the action heats up, readers will find themselves in a dead sprint to see who, if any, makes it out alive.
This one sizzles. Jack Stewart, one of the brightest new stars in the thrillersphere, always dials things way up, so seeing him team with Chad Robichaux was sure to make headlines. But whether or not they could deliver a story worth the hype was the real question—and for what it’s worth, I think they’ve outdone themselves. There’s definitely a ton of action, all told with the kind of authenticity that’ll have you ducking for cover as you turn the pages, but what really sets Silent Horizons apart is its emotional core. Foster Quinn isn’t just a warrior—he’s a father, a husband, and a man struggling with loss and guilt. The inner conflict makes his mission all the more compelling, anchoring the action in a powerful human story. The climactic payoff is both explosive and emotionally resonant, capping off with a satisfying conclusion that’ll no doubt leave readers eager for the next installment.
Perfect for fans of Jack Carr’s Terminal List or Mark Greaney’s Gray Man series, Silent Horizons blends covert operations, geopolitical intrigue, and personal sacrifice into a riveting package. Robichaux and Stewart have crafted a powerful first entry, laying the foundation for a series with real staying power. Count me among those who are eagerly waiting to see what they do next.
