Ember Series. Ember Boxset, #1

At age sixteen, Matt goes to Denmark as an exchange student to learn of his deceased father's heritage. Finding an old Norse god on the family tree was not expected. With that discovery, the Vargr ember in him responds to pack, meaning Matt needs to learn a whole lot more than the Danish language. He needs to learn to control an angry ember which is the power source of the Alpha rising in him. That strength in Matt is needed because other powerful Alphas don't like Matt's pack alpha, Steffen. An old law is taken into play to see Pack Alpha Steffen fall from grace.
There seem to be more sinister motives than taking down a single pack Alpha, though, and Matt's powerful ember will roar.
