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. Author Note: Hostile Heir is a duet within the Hostile Kingdom World. There is a HEA in the second book, Hostile King. It's a forced proximity dark romance that includes scenarios and references which may act as a trigger to some readers.
