An Arranged Marriage Mafia Romance
Heather's given to Mafia King Ari Levinsky in an arranged marriage to create an alliance with her terrible mobster dad. She's supposed to be touring Europe after graduating from college, but before she can blink she's standing at the altar trying to read her vows in... Aramaic? Heather's new husband is gigantic; tall, muscled, terrifying, and loud. And she doesn't even get to pick out her own wedding dress! Then, it's on to a romantic beach honeymoon, so much double-crossing, and she finds the only way to outsmart her scary, ridiculously hot husband... is to out-sex him.
Severity reflects intensity, not value — “central theme” means a warning is a core part of the book, not that the book is bad.
