Hostile Heir by Autumn Archer

Once upon a time he set me free. This time it won’t be that simple.
I can’t stop wondering why the cartel heir with mafia blood in his cold veins saved me all those weeks ago. The young virginal misfit who was kidnapped and gifted to a villainous kingpin.
But he did.
And I was wrong to think he was my hero.
I never expected to meet Tomás Souza again. Or that I’d be covered in his father’s blood. However, fate has brought me face to face with a vengeful monster who’s blinded by wrath.
Now, I’m his captive while he claims a merciless throne—and my innocence.
Except he underestimates me. They all do.
No matter the bond we share, our agreement must end, especially when the newly crowned king has a heart-shattering secret.
