Firebound

Scarlet Caruso was born into power.
The only daughter of the most feared Italian mafia family, she has spent her entire life surrounded by danger, loyalty, and men who would kill for her without hesitation.
But the one person who has always stood closest to her... was never supposed to matter the most.
Kyle Santoro grew up with nothing except bruised knuckles, a violent home, and the underground fight clubs that kept him alive. When the Caruso family found him, they didn't just give him protection - they gave him a purpose.
Now he's one of their most trusted guards.
And Scarlet's shadow.
They grew up together.
But in a world where loyalty is life and betrayal means death, feelings like theirs were never meant to exist.
Because falling for the mafia princess?
Is the one line Kyle Santoro was never supposed to cross.
And once he does...
There's no going back.
