The Don by Margaret McHeyzer

Eliza: Ruben is my husband’s uncle, and the Don of the Sacco Mafia—he’s dangerous yet fiercely protective.
Even before I married Adrian, I knew he wasn’t a good man. From the moment he laid eyes on me, I became his property. The things he put me through are what nightmares are made of. So I did the only thing I could; I fled to live with my sister, Rose.
But no one leaves Adrian Sacco without consequences.
Ruben: As soon as I saw Eliza in her wedding dress she took my breath away. But she was marrying my nephew, who’s also my underboss. Out of respect, I couldn’t act upon my feelings.
But everything changed when he laid his hands on her, and she escaped.
She’s forced to stay with me while Rose and Dominic are on their honeymoon. I know she’s been through hell, but having Eliza close only makes me want her more.
With trouble brewing since Adrian wronged the family, then disappeared, my first instinct is to protect her.
Despite our age gap, I’m going to make my amorina mine.
