Fallen heiress Serafina is married off as a union bargaining chip to Marcello, the second son of a gang family, only to discover his infidelity on their wedding night and be reduced to an abused and humiliated prisoner. Dominic, the cold-blooded tyrant who rules North America’s underground empire, returns to avenge an old family blood feud and launches an aggressively forbidden seduction of Serafina right under his brother’s nose. What begins as a vengeful game filled with hidden touches under banquet tables and desperate kisses in darkened blackout corridors soon makes the arrogant Don fall irrevocably in love. When the lies collapse and Serafina flees in despair, the ruthless tyrant humbly begs for her forgiveness in the pouring rain. After Marcello abducts her, Dominic descends like the reaper and executes his own brother with a fatal shot. Amid blood and terror, he places the supreme ruby power ring on her finger, crowning the once trampled girl the one and only queen of the underground empire in a sweeping mafia romance of intense tension, forbidden morality, and obsessive, twisted favoritism.
