With the discovery of gold in the Rocky Mountains, prospectors have been coming closer to Wild Lands Ranch. Henry Abbey is determined to protect his family's land, and the wolves are too. Henry doesn't know they exist, but they've been watching him for a long time and one is closer than he even realizes.
Justus is a young wolf who has been working on the ranch to keep an eye on the humans and make sure they keep their part of the bargain. The plains belong to them, but the forest is the territory of the wolves. He likes Henry and wishes he could tell Henry everything he knows about the wolves and the pact, but it's forbidden.
The rules begin to change on both sides when miners come into the forest looking for gold. The wolves need help, and the humans need the men off their land. When Justus reveals himself while protecting Henry, they are tied together forever.
