The Prince's Mate (The Prince's Mate, Pt 1) by Hayden West
In Alaska for a vacation, Zachary Adan, runs into a man who will change his life. All it takes is one night run on the slopes and everything he has known and believed is brought into question.
Chase often comes to this resort when he wants to get away from his responsibilities. This time, he meets his mate and understands why he was drawn back so soon.
During a night run, opposing forces attack them and sooner than he wished, he must reveal to Zach who he truly is; Prince Chamber Sept Mallo. Not only must he keep his mate alive so he can take his place on the throne, but he must also convince the man to stay with him for the rest of their lives.
