Demon Rapture — Lee Pearce

Two demon gods, celestial opposites, paired for eternity by love, manipulated by the dying children of their world to create a new race then forced apart in exile; lost in a netherworld never able to love each other; resurrected five thousand years later by evil forces seeking to have them destroy what they lovingly created. Now they just have to find each other in time to set the world right once again.
