Rocky Mountain K-9 Unit sets the K-9 action against mountain terrain. All nine books were published in 2022, from Detection Detail through Christmas K-9 Unit Heroes.
Ready to Protect, Hiding in Montana, and Undercover Assignment establish the mountain setting, while Defending from Danger, Tracking a Killer, and Explosive Revenge raise the stakes. Rescue Mission leans into the search-and-rescue aspect that the mountain environment naturally provides.
