4 books

Set against the vast, unforgiving landscape of rural Montana, this series follows Cassie Dewell — a deputy-turned-private investigator whose cases drag her into the darkest corners of the American West. Box captures the isolation and danger of the high plains with cinematic precision, and the series became the basis for the hit ABC drama Big Sky. Taut, atmospheric crime fiction with a protagonist whose moral compass never wavers no matter how bleak the territory gets.
