Harvey’s coming back to where it all started… A “philanthropist” arrives at Yellowstone with the cure to a global helium managed venting, precision valves, and a camera crew to sell the miracle. When those valves turn out to be detonators and the miracle is really a market play, Harvey “Ben” Bennett and the Civilian Special Operations team are dragged back to the place where his story began—into blinding steam, trench-cold wind, and a ticking clock buried under the world’s most dangerous caldera. With Juliette coordinating from their Alaska HQ, Reggie running and gunning in the snow, and a stolen lab routine threatening to punch new holes in the basin, Ben has to hold the pressure steady and rip the mask off a savior who engineered the crisis he’s “solving.” The key to blowing it wide open isn’t a weapon—it’s a confession. A trail of shell companies, and proof that could shake D.C. before the ground does. From knife-edge helicopter extractions to midnight gunfights beside hissing vents, The Yellowstone Gambit delivers breakneck action, big-idea stakes, and a conspiracy that turns charity into a weapon. If Ben can’t shut it down, Yellowstone won’t be the only thing that blows.
