Hunted by a killer. Trapped by the wild. In Yellowstone, everything wants you dead.
When Jane witnesses her father’s murder during a routine wolf?research trip, she’s forced into a deadly race for survival through blizzards, bison, and a stalking predator who knows the terrain better than she does. Teaming up with Colm—another target—may be her only chance, but the wilderness is as ruthless as the man hunting them.
The Kill Line delivers a fierce, breathless fight to stay alive in America’s most dangerous park. $4.99 on Kindle.
