- Description from novelbuddy

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

A wedding forged in vengeance, where love is the only risk they never planned for.“Let's get married,” Mia says, her voice trembling despite the fire in her eyes as she meets Stefan's guarded gaze. She needs this—needs him—even if he looks at her like she's just another complication.Stefan arches a brow, unimpressed. “And why would I do that?”“We both know what it's like to be betrayed by the men who raised us,” she replies, refusing to back down. “They stole our birthrights and handed them to someone else. The only difference is… you're the illegitimate one. I'm not.”He studies her—this heiress in designer armor, hiding rage beneath polish. “So your grand plan is a wedding band as revenge?”“No,” she says, stepping closer, close enough for him to smell the jasmine and gunpowder. “It's the only weapon they won't see coming.”Their fathers built empires by manipulation and control. Now, their children are making a vow—to burn it all down.Two shattered heirs. One dangerous alliance. A marriage built on vengeance.Mia Meyers was born to inherit her father's empire—until he handed it to his bastard son instead. Stefan Sterling knows rejection too well, discarded by a father who only valued power. Now, these rivals-turned-co-conspirators hatch a plan: marry for revenge, crush their fathers' legacies, and take what should've always been theirs.No love. No feelings. No divorce.But as lines blur between strategy and obsession, the real question becomes: can two enemies survive a marriage built not on trust—but on spite?
