Sold to the Devil of Madrid. Spanish Royal Bastards Mafia, #1

She stepped onto that stage to save her sister. She didn't expect anyone to save her. Daisy Evans is nobody's idea of a mafia prize. A part-time library assistant working two jobs to keep her family afloat, the twenty-two-year-old has no business at a West End virgin auction-except her reckless, debt-riddled father has sold her little sister to the most sadistic Bratva kingpin in London. To protect her, Daisy does the only thing she can think of: she takes Rose's place.
The plan is simple: Survive one night. Wipe out the debt. Start over. What she doesn't plan for is the Devil of Madrid. Angel Reyes, the head of the Spanish Royal Bastards Mafia, didn't come to London's most dangerous backroom auction to buy anyone. At forty, he's carved out an empire from bloodshed and sacrifice, and he long ago buried the part of himself that wanted more. Then Daisy Evans wobbles onto that stage in an ill-fitting dress and borrowed heels, and something in him, something Angel thought was dead, refuses to stay quiet.
Now he has to figure out what to do with an innocent woman, who isn't afraid of him, sees straight through him, and is slowly dismantling every wall he's spent a lifetime building. She was meant to be a pawn. He was supposed to be a monster. Neither of them is what the other expected. But sometimes the person you never saw coming is the one you needed all along.
