Cassie Dewell returns in this thrilling new read from the series that inspired the hit TV show Big Sky, from award-winning 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. 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 investigating rumours of buried treasure somewhere in the vicinity of Anaconda, Cassie has her hands full.

The highly anticipated new thriller from New York Times bestseller C.J. Box, Treasure State is full of more twists and turns than the switchbacks through the Anaconda Range.

Reviewers on the Cassie Dewell books:

'Excellent... Box has rarely been better.' Publishers Weekly

'Cassie Dewell is a complex and multi-faceted protagonist.' Book Reporter

'Joe Pickett may be Box's main man, but Cassie is equally compelling... Box has become the dominant mystery/thriller author of the mountain West – and deservedly so.' Booklist
