Obsession: Christian & Mia by Fiona Davenport

Christian DeLuca was born into a powerful mafia family, but he’s chosen a different path for his own life. Returning home for his niece’s christening, the last thing he expects is to fall for a beautiful artist with ties to his family.
Mia Ricci is instantly attracted to the sexy professor, but a relationship between them is impossible. If he knew about the work she’s been doing for his cousin, he’d condemn her.
But Mia doesn’t realize that she’s quickly become Christian’s obsession…and he’s not willing to give her up for anything.
