Joe Pickett's old friend, Nate Romanowski, is off the grid, lying low while the FBI search for him. But they're not the only ones looking for him. Nate finds himself confronted by agents who need his help assessing a potential terror threat in Wyoming's Red Desert. In return they'll make Nate's criminal record disappear. Meanwhile, Joe investigates a rash of crimes and secretive federal activity. As they pursue their quarries, both men will be drawn deep into a secret that could take them both down.

Everything about the ranch is a mystery. Rumours abound about the millionaire who owns it, the women who live with him, and the sudden disappearances. Joe Pickett is tasked by the governor to find the truth. There are two other men living up at the ranch. One is a stone-cold killer who takes an instant dislike to Joe. The first man doesn't frighten him. But the second is another story entirely.

The plane circled in the dark. Down below, Joe Pickett could just make out figures in the snow and timber. Joe knew that he might be their next target. The Cates clan's history with the Picketts is about to come full circle. Game warden Joe Pickett struck a fierce blow against them when the life of his daughter April was endangered. But it wasn't a killing blow, and he'd always wondered if there'd be a day of reckoning...It seems now Joe will find out.

Wyoming's new governor isn't sure what to make of Joe Pickett, but he has a job for him that is extremely delicate. A prominent female British executive never came home from the high-end guest ranch she was visiting, and the British embassy is pressing hard. At the same time, his friend Nate Romanowski has asked Joe to intervene with the feds on behalf of falconers who can no longer hunt with eagles even though their permits are in order. But the more he investigates both cases, the more someone wants him to go away.

The good news is that Joe Pickett has his job back. The bad news is that Wyoming's Twelve Sleep County game warden is only days away from the most dangerous predators he's ever faced. Joe's working with Katelyn Hamm, his counterpart in adjacent Shell County, to trace a drone operator whose aerial acrobatics have been stampeding elk and deer to their deaths. Their investigation will put them both on a collision course not only with the FBI but also with the Wolf Pack, a remorseless quartet of killers.

Butch Roberson was known by all as a local business owner, a hard worker, and a family man. Then he disappeared, leaving two dead bodies in his wake. Now he's known as a murderer - though Joe Pickett cannot believe someone as gentle as Butch could have the instincts of a killer.

Joe Pickett’s in his last week as the temporary game warden in the isolated town of Baggs, Wyoming, but there have been strange things going on in the surrounding mountains, and his conscience won’t let him leave without checking them out: reports of camps looted, tents slashed, elk butchered. And then there’s the runner who’s gone missing – an Olympic hopeful who’d been training in the region and then just ... vanished.

In 1995, Nate was in a secret Special Forces unit abroad when a colleague did something terrible. Now high up in the government, the man is determined to eliminate anyone who knows about it, and Nate knows exactly how he'll do it – by striking at Nate's friends to draw him out. The entire Pickett family will be a target, and the only way to fight back is outside the law. Nate knows he can do it, but he isn't sure about his straight-arrow friend – and all their lives could depend on it.

'Tell Sherry April called.' That simple phone message shakes Joe Pickett’s oldest daughter Sheridan and the rest of the family to the core. To Joe, it doesn’t seem even remotely possible that April could have survived the massacre six years before. He was there, and he was unable to save her. But Sheridan starts to believe there’s a chance that April is still alive, and her suspicions are confirmed when the person sending texts to her cell phone is able to recall family incidents only April could know.

It’s elk season in the Rockies, but this year one hunter is stalking a different kind of prey. When the call comes in on the radio, Joe Pickett can hardly believe his ears: game wardens have found a hunter dead at a camp in the mountains - strung up, gutted, skinned, and beheaded, as if he were the elk he’d been pursuing. Governor Rulon is forced to end hunting season early for the first time in state history - outraging hunters and potentially crippling the state’s income from the loss of hunting license revenue.

It’s an idyllic late-summer day in Saddlestring, Wyoming, and game warden Joe Pickett is fly-fishing with his two daughters when he stumbles upon the mutilated body of a moose. Whatever or whoever attacked the animal was ruthless: half the animal’s face has been sliced away, the skin peeled back from the flesh. Shaken by the sight, Joe starts to investigate what he hopes is an isolated incident.

When Earl Alden is found dead, dangling from a wind turbine, it's his wife, Missy, who is arrested. Unfortunately for Joe Pickett, Missy is his mother-in-law, a woman he dislikes heartily, and now he doesn't know what to do - especially when the early signs point to her being guilty as sin. But then things happen to make Joe wonder: Is Earl's death what it appears to be? Is Missy being set up?

Cody Hoyt, while a brilliant cop, is an alcoholic struggling with two months of sobriety when his mentor and AA sponsor Hank Winters is found burned to death in a remote mountain cabin. At first it looks like the suicide of a man who’s fallen off the wagon, but Cody knows Hank better than that....

Joe Pickett, having recently been fired from his job as a Wyoming game warden, is working on his father-in-law’s ranch when he receives a call. Governor Rulon - a devious but down-home politico - has a special request. Clay McCann, a lawyer who slaughtered four campers in cold blood in a far-off corner of Yellowstone National Park, had immediately turned himself in at the nearest park ranger station - except that the crimes were committed in a thin sliver of land with zero residents and overlapping jurisdiction, the so-called free-fire zone.

A 12-year-old girl and her younger brother go on the run in the woods of northern Idaho, pursued by four men they have just watched commit murder - four men who know exactly who the children are, and where their desperate mother is waiting patiently by the phone for news of her children's fate.
