Cassie Dewell returns in this thrilling new read from the series that inspired the hit TV show Big Sky, from New York Times bestselling author C.J. Box.

Investigator Cassie Dewell 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.

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 the truth. Between searching for the con-man and investigating rumours of buried treasure somewhere in the vicinity of the town, Cassie has her hands full.

For fans of Big Sky and Yellowstone, Treasure State is full of more twists and turns than the switchbacks through the Anaconda Range.

'C.J. Box is the crime fiction bard of American's northern plain states.' Toronto Star
