Why we recommend it

A ruthless empire opener where oaths bind and vengeance simmers beneath every vow. The hero is cold, dangerous, and utterly possessive, the stakes lethal, and the slow thaw of an unwilling union half the thrill. For readers who want their mafia romance heavy on menace, power plays, and the dark gravity between a cruel man and the woman who won't break, it's a commanding, high-tension launch into a brutal new world. Ruthless to the core.
