The Warrior's Ascension — E.A. Reynolds

[Siren Classic ManLove: Alternative, Fantasy, Witches/Demons, Interracial, Action/Adventure, Romantic Suspense, MM, HEA] Dallan wasn’t expecting his downtime to last long, but the peace is shattered when Dallan learns six notorious demons who have been vanquished to a box have found a way out. Not only that, but they are also gunning for members of the triangle. To defeat them, Dallan will have to become the mage he never knew was possible and make alliances with demons who could one day become the enemy. Dallan knows it will take all he has to play his new role, a roll that could test his relationship with Hansel, but Dallan has no choice. His God just might force him to put duty before love again to win this war and train the new powers that will fight with him. On the other hand, Hansel is determined to make things work between he and Dallan and is more than willing to go all in for love.
