#1 New York Times bestselling author Jack Carr never misses—and this time, he doesn’t just raise the stakes . . . he burns the whole system down.
Set outside his mega-bestselling James Reece universe, Carr, who by all accounts has proven to be atop the food chain of today’s modern thrillersphere, brings on his first co-author, fellow New York Times bestseller M.P. Woodward (Tom Clancy’s The Coldest War, etc.), to introduce a brand new hero in former Navy SEAL and CIA ground branch operative Chris Walker—a character very much cut from the same cloth as Reece, but battling a whole different set of demons.
The story still hits with the force of the The Terminal List series, but in a lot of ways, The Fourth Option punches a little deeper.
Right off rip, readers meet Chris Walker—who, following a TBI, is medically retired—at rock bottom, sitting on the sofa of his customized ’84 Volkswagen Westfalia Vanagon, his weighty 1911 in his hand, ready to punch his own ticket and end the pain he’s carried since losing John Staub, his close friend and teammate, in Afghanistan. Then his phone chirps, announcing the arrival of a new text message—the sender offering him a lifeline in the form of a new mission that gives him renewed purpose.
And a reason for him to put that 1911 back to work, sighting new enemies who need to be dealt with.
In an ironic twist, the sender is none other than Leigh Ann Staub, the wife of the late John Staub, Walker’s master chief in the SEAL Teams, whose death Chris blames himself for. Right as he’s about to take his own life, ending the guilt and pain he can’t seem to quiet, the man’s widow explains that she needs Walker’s help—immediately.
As it turns out, Connor Staub, John and Leigh Ann’s son, has been murdered. While the police don’t seem all that interested in conspiracy theories, Leigh Ann tells Walker that she knows exactly why her son was targeted, even if she doesn’t know who, specifically, killed him. She explains that Connor, an NYU grad pursuing a master’s degree at Columbia University Journalism School, had stumbled upon a story. A big story. The kind that people will kill without hesitation to keep it under wraps.
Walker listens as Leigh Ann explains that Connor had spent the last year or so investigating the drug trade. To the best of her knowledge, his focus was on a new, synthetic drug that makes fentanyl look like Tylenol. She has all of Connor’s notes, which are mostly coded, but point to bribes and hush money being thrown around, and even without a background in law enforcement, Leigh Ann knows that it’s always about following the money. Walker knows that too, and feeling indebted to the Staub family, agrees to poke around and see what he can uncover.
Once the investigation starts, so do the fireworks, and soon, Walker—armed only with the weapons he’s stashed in his pop-up-camper-turned-armory and his trusty wardog, Paladin—finds himself going to war against the very system he swore to protect.
Moving from slow-burn ignition into a full-blown inferno, The Fourth Option wastes no time exploring corruption, betrayal, and the kind of evil that doesn’t just slip through the cracks but hides behind the system itself. It’s familiar enough that Carr’s legion of fans will feel right at home, but different enough to keep them off balance and guessing, even when they think they’ve got it all figured out.
Whereas Carr’s other works are more geopolitical and military-driven, there’s a clear Western influence running through this one—the lone gunslinger riding into town to right a wrong nobody else will touch. It’s Unforgiven meets modern-day counterterrorism, with just enough grit and moral gray area to keep things unpredictable. Flashback sequences show the relationship between Walker and John, while the present-day action drags readers from one action scene to the next. It’s clear the dual timelines will cross at some point, but good luck figuring out when and where.
Ultimately, what makes this story and this writing team so effective is that Carr and Woodward know exactly when to step on the gas, when to let the tension simmer, and when to throw in a twist their readers won’t expect. The result? an unforgettable thrill ride that’s sure to challenge for best book of the year.
And because I know that readers will want to know how Walker differs from James Reece… Without spoiling anything, Reece (especially early in the series) is driven by righteous anger, the pursuit of justice, and ultimately, love of country. While shades of that are true for Walker, Chris is smaller in stature than James, less physically imposing—more wiry (bonus points if you read that in your best Nigel Gruff voice) than huge, and more driven by the kind of guilt that’s left him with nothing to lose, making him a different type of dangerous. Think Martin Riggs in Lethal Weapon (the 1987 movie, obviously, not the TV show) and you’re not far off.
Bottom line: some thrillers entertain. This one asks a question you won’t be able to shake, and if it doesn’t make you uncomfortably, you probably weren’t paying attention.
Pre-order with confidence, then clear your schedule and don’t plan anything until you’ve turned the final page. The Fourth Option is Jack Carr evolving as a storyteller, taking bigger risks, asking harder questions, and proving once again why he’s one of the most important voices in publishing today.
