Don's new pack alpha is insane, and they are all in danger as long as he holds the power, which is why his pack brings in another alpha to fight Zane. Don wouldn't have a problem with that, except that Rhys is his mate. Rhys had been poisoned to lose the fight for the alpha position in his birth pack and is unwilling to trust anyone, especially not the pack who wants him to kill their alpha. Even if he is attracted to Don, it doesn't mean the other man is someone he should trust. He still hasn't come to a decision whether to risk another alpha challenge or not when Zane does one thing he won't forgive. He kidnaps Don. Now Rhys is left with no choice.
