As Cody makes his way to the lonely stretch of Montana highway where they went missing, Cassie discovers that Gracie and Danielle Sullivan aren't the first girls who have disappeared in this area. This majestic landscape is the hunting ground for a killer whose viciousness is outmatched only by his intelligence. And he might not be working alone. Time is running out for Gracie and Danielle… Can Cassie overcome her doubts and lack of experience and use her innate skill? Can Cody Hoyt battle his own demons and find this killer before another victim vanishes on the highway?

Grimstad, North Dakota – a place people used to be from, but were never headed to – has struck oil. As pipelines snake across the prairie, oil flows out and men and money flow in. And with them, comes crime. North Dakota’s new oil capital has a serious law and order problem and newly qualified detective Cassie Dewell has just been assigned as its deputy sheriff. Twelve-year-old Kyle Westergaard is one of Grimstad's paperboys. Even though Kyle has been written off as the “slow” kid, he has dreams deeper than anyone can imagine – he wants to get out of town, take care of his alcoholic mother, and give them a better life. While delivering newspapers, he witnesses a car accident and now has money and a lot of white powder in his possession. With the temperature dropping to 30 below and a gang war heating up, Cassie fears she might be in over her head but the key to it all will come in the most unlikely form: an undersized boy on a bike who keeps showing up where he doesn’t belong.

For three years, Investigator Cassie Dewell has been on a hunt for a serial killer known as The Lizard King. He works as a long haul trucker. His prey are the "lot lizard" prostitutes who frequent truck stops. And she almost caught him...once. Working for the Bakken County, North Dakota sheriff's department, Cassie has set what she believes is the perfect trap and she has lured him and his truck to a depot. Standing by, ready to close the net are half a dozen undercover officers, including Cassie's fiancé Ian. But the plan goes horribly wrong, and the blame falls to Cassie. Disgraced, she loses her job and investigation into her role is put into motion. At the same time, Kyle Westergaard, a troubled kid whom Cassie has taken under her wing, has disappeared, telling everyone he is going on a long-planned adventure. Kyle's grandmother begs Cassie to find him and with nothing else to do, she agrees—all the while planning a new trap for The Lizard King. But Cassie is now a lone wolf. And in the same way that two streams converge into a river, Kyle's disappearance may have a more sinister meaning than anyone realizes. With no allies, no support, and only her own wits to rely on, Cassie must take down a killer who is as ruthless as he is cunning. But can she do it alone, without losing her own humanity or her own life?

A riveting new novel from the New York Times bestselling and Edgar-Award winning author. Former police officer Cassie Dewell is trying to start over with her own private investigation firm. Guilty about not seeing her son and exhausted by the nights on stakeout, Cassie is nontheless managing...until an old friend calls in a favor: she wants Cassie to help exonarate a man accused of assaulting a young girl from an influential family. Against her own better judgment, Cassie agrees. But out in the Big Sky Country of Montana, twisted family loyalty runs as deep as the ties to the land, and there's always something more to the story. As Cassie attempts to uncover the truth, she must fight against the ghosts of her own past that threaten to pull her back under.

The return of Cassie Dewell in Treasure State, the latest in the series that inspired the ABC hit series Big Sky, finds Cassie in Montana on the trail of a con man. Investigator Cassie Dewell—now the lead character in this year's most sensational TV crime show, Big Sky, from Big Little Lies creator David E. Kelley—is headed to Anaconda, Montana, in search of a slippery con man who has disappeared somewhere in the "treasure state". A wealthy California divorcee has accused him of absconding with her entire fortune, and wants Cassie to find him and get it back. But Anaconda, a quirky former copper mining town, is the perfect place to reinvent yourself, and as the case develops, Cassie begins to wonder if her client is telling her everything. Between searching for the con man and a second case, that of a rumored buried treasure somewhere in the vicinity that has led to a cutthroat competition among adventure-seeking treasure-hunters, Cassie has her hands full. C. J. Box's newest Cassie Dewell novel, the highly anticipated follow-up to The Bitterroots, is full of more twists and turns than the switchbacks through the Anaconda Range.
