Burned by My Ex, Reborn as His King's Mate

Seraphina died betrayed. She perished in flames—poisoned by Darius, the fated mate she'd foolishly loved. Her childhood sweetheart, who sacrificed her only to save his mistress.
Reborn five years earlier, Seraphina vows: Never again. No more submissions. No more suffering his cruelty. This time, she'll rewrite her destiny - then she meets Kairos.
The Untamed Alpha King who loathes the mate bond after his own betrayal. Her second-chance mate - a bond that will kill her if she rejects it.
Now, caught between Kairos' relentless pursuit and Darius' desperate attempts to reclaim her, Seraphina faces an impossible choice:
Drown the world in vengeance... or risk her shattered heart on the mate who could either heal her scars or destroy her completely?
