The Demon King's Final Tier

Cold secrets bind Carmine, my tormented demon-king mate, while a hidden ancient power threatens him and a world of supernaturals.

I hated him for three years and planned to kill him, until the wrath curse put an end to that plan.

Standing any chance of saving him means breaking my oath and completing our mating rituals.

If I surrender to the bond, my fate merges with his, so his death would take me too and leave our son alone against that enemy.

The final tier of this battle may demand more than I can risk.
