Joe Picket, 7-12

Free Fire
Joe Pickett's been hired to investigate one of the most cold-blooded mass killings in Wyoming history. Attorney Clay McCann admitted to slaughtering four campers in a back-country corner of Yellowstone National Park - a 'free-fire' zone with no residents or jurisdiction. In this remote fifty-square-mile stretch a man can literally get away with murder. Now McCann's a free man, and Pickett's about to discover his motive - one buried in Yellowstone's rugged terrain, and as dangerous as the man who wants to keep it hidden.
Blood Trail
Game wardens have found a man dead at a mountain camp-strung up, gutted, and flayed as if he were the elk he'd been hunting. Is the murder the work of a deranged anti-hunting activist or of a lone psychopath with a personal vendetta? Wyoming game warden Joe Pickett is the man to track the murderer and stop him, before someone declares open season on humans...
Below Zero
Six years ago, Joe Pickett's foster daughter, April, was murdered. Now, someone is leaving phone messages claiming to be the dead girl. As his family struggles with the disturbing event, he discovers that the calls have been placed from locations where serious environmental crimes have occurred. And as the phone calls grow closer, so does the danger...
Nowhere to Run
It's Joe Pickett's last week as a temporary game warden in the mountain town of Baggs, Wyoming, but his conscience won't let him leave without checking out the strange reports coming from the wilderness: camps looted, tents slashed, elk butchered. What awaits him is like something out of an old campfire tale, except this story is all too real-and all too deadly.
Cold Wind
A body hangs from a wind turbine, a bullet hole in his chest: Earl Alden, millionaire property developer. His wife, Missy, is the prime suspect. It wouldn't be a problem for Joe Pickett, if Missy weren't his mother-in-law. Missy claims she's innocent, and for his wife's sake, Joe would like to believe her... but all the early signs point to her being as guilty as sin. With his wife on one side and the law on the other, Joe needs to get to the truth before his family is ripped apart.
Force of Nature
Years ago Joe Pickett's best friend, Nate Romanowski, was in a Special Forces unit abroad when his commander, John Nemecek, did something terrible. Now the high-ranking government official and cold-blooded sociopath is determined to eliminate anyone who knows about it - like Nate, who's hidden himself away in Wyoming's Bighorn Mountains. And he knows exactly how Nemecek will do it-by targeting Nate's friends to draw him out. That includes his friend, game warden Joe Pickett, and Pickett's entire family. 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.
