Can a K-9 team stop an assassin with a deadly plan?
When someone shoots at volcanologist Aubrey Smith on Mount St. Helens, it’s up to K-9 officer Isaac McDane to protect her even though she broke his heart a decade ago. But as people keep dying and signs point to Aubrey’s sister being involved or the next potential victim, they’ll have to work together to track down the killer before he finishes his hit list.

In the shadow of the towering peaks and dense evergreen forests of the Pacific Northwest, danger is never far behind. The Pacific Northwest K-9 Unit is a high-octane continuity series following elite law enforcement officers and their canine partners as they protect the innocent across rugged national parks and treacherous wilderness.
From tracking serial bombers in Olympic National Park to dismantling drug rings undercover, these teams face relentless adversaries. In Sharon Dunn’s gripping entry, Threat Detection, K-9 officer Isaac McDane must protect volcanologist Aubrey Smith on the volatile slopes of Mount St. Helens. When a sniper’s hit list puts Aubrey and her sister in the crosshairs, Isaac and his loyal K-9 partner must brave the elements and a decade of complicated history to stop a killer before the mountain—or a murderer—claims another victim.
Whether rescuing kidnapped children, clearing the names of the falsely accused, or surviving a brutal winter storm, the heroes of the Pacific Northwest K-9 Unit rely on their sharp instincts and their dogs to bring justice to the wild.
