Daughter of two empires

Elle Rose Kostas was never meant to survive.
Found at seven in a dungeon full of monsters, adopted by the Greek Mafia's most feared don, she grew into something far worse than anyone expected-deadly, unhinged, loyal only to the man who saved her and the three soldiers she trusts with her life.
To her enemies, she's a ghost story.
To the underworld, she's a warning.
To her father, she will always be "my girl."
But when a single night of fire exposes her existence, the mafia world finally learns the Greek Don has a daughter-one who kills with a smile, dances through flames, and laughs in the face of men who beg for mercy.
And suddenly, everyone wants her.
A family that looks just like her.
A man who should hate her but can't stop thinking about her.
But she just wants her knifes and fire...
