The Texas K-9 Unit series takes the K-9 unit formula to the Lone Star State, with eight books all published in 2013. Tracking Justice, Detection Mission, Guard Duty, and the other entries follow Texas law enforcement handlers and their K-9 partners through interconnected cases.
The series was one of the earlier K-9 unit franchises in the Love Inspired Suspense line and helped establish the format that would be repeated with Capitol, Military, Alaska, and Brooklyn settings.
