Of Blood and Briar (Briar Soul #1) by Kaitlyn Rouhier

"Every soul has a price." After Calder’s village is brutally attacked, he seeks revenge against those responsible. Taken as a prisoner, he waits for an opportune moment to strike, and his bloody vengeance catches the eye of Amari, an assassin from a distant land. Invoking an ancient rite, she claims Calder as her apprentice, sparing his life but tethering him to an uncertain fate. Taken across the sea to the dying lands of Vermund, Calder is thrust into a world plagued by ancient beings and dark magic. It is there he finds himself caught in a conflict between the old ways in the North, and the growing threat building in the South, a struggle that could cost him everything, even his very soul.
