Catalina D'Angelo and Mikhail Morozov come from worlds built on power, loyalty, and betrayal—and their paths were never meant to cross. When Catalina's brother is taken, she's forced into an uneasy partnership with Mikhail, a man as dangerous as he is enigmatic. Beneath their sharp tension and constant mistrust simmers a connection neither is ready to face.

As they navigate a deadly game of secrets, violence, and shifting loyalties, Catalina's fierce independence clashes with Mikhail's calculated control. Yet beneath the hardened exteriors, a fragile truth begins to surface—one that threatens to unravel everything they thought they knew about themselves and each other.

Caught between past wounds and uncertain futures, Catalina and Mikhail must decide: is their bond a fragile alliance forged by necessity—or the beginning of something real?

King of Ruin is a slow-burning, enemies-to-lovers romance full of danger, trust, and the kind of love that rises from the ruins of a broken world.
