Rise of the Serpent Goddess

"On the northern border ruled by orc tribes, orphan Elena is offered by her people as a peace sacrifice to Marcus, the brutal three-hundred-year-old serpent clan leader. Despising humanity’s frailty, Marcus plans to imprison her as his plaything after the blood ritual. Yet when he pierces her neck with his fangs to seal the blood pact, the ancient primordial serpent god blood within Elena awakens. The pact backfires, siphoning Marcus’s power and binding their souls—if one dies, the other perishes too. Elena leverages this bond to aid abused half-orcs, fend off rival tribes, and tame an abyssal python feared even by Marcus. He grows drawn to her, revealing his trauma of human betrayal that slaughtered his kin. When human kingdoms ally with rebel orcs to attack, Elena awakens ancient orc legions via the serpent totem with her blood, abolishes the unequal pact, and forges a new covenant of equality between humans and orcs. Marcus submits to her, and Elena becomes the first queen revered by both humans and orcs across the Northlands."
