Synopsis：After the Great War, humans, vampires, werewolves, and elves signed a pact: hybrid heirs would rule the world. Every century, political marriages between humans and the three clans decide the next ruler—whoever bears the first hybrid child seizes power for their bloodline. In my past life, I chose to marry Jax, the eldest son of the werewolf pack, infamous for his brutal loyalty. I gave birth to our white-furred pup, Zeal, who rose as the new world sovereign, granting Jax unshakable power. My sister, blinded by her obsession with elven beauty, married into the elves, only to discover the prince shared his bed with every female in the forest. In the end, she caught a terrible disease and became barren. Consumed by jealousy, she set a fire that burned me and my young pup alive. When I opened my eyes, I was back on the day of the alliance marriages. My sister had already spent the night with Jax. I knew then—she had been reborn too. But she had no idea that Jax turned savage in heat, having torn countless she-wolves apart in his bed.
