Sequel to Darkness ThreateningYellowstone Wolves: Book Three The last thing Tobias, alpha of the small Greenview Pack, expects is to find a lost human asleep in his storage building. As soon as he sets eyes on Pete, Tobias knows they are destined mates. But he cannot act on his attraction, no matter how much he feels compelled. Exposure to the human world could mean the end of their way of life, so he decides to help Pete get a room until he can reunite with the tour group he separated from. But Tobias's disgraced half brother, Zev, has other ideas. He takes a liking to Pete and decides he wants what Tobias has-both his position as pack leader and his mate. Tobias can't let that happen, but protecting Pete means keeping him close, which only increases the mounting tensions between them. Duty, protection, desire, and secrecy clash as the darkness within Zev rises to the surface, and only Tobias can save his mate-even if he never plans to tell Pete that's what they are.
