Passion (Mafia Ties #3) by Fiona Davenport

Being part of rival families wasn’t enough to stop the passion between Brandon DeLuca and Carly O’Reilly. They’ve defied the odds and prevailed together as a couple, the first female to lead her Irish mob family and the Italian enforcer who stands by her side. When one of her enemies tries to use Carly as a pawn in an attempt to gain power, Brandon is out for blood—saving Carly isn’t enough.

Please note: Brandon & Carly’s romance is a three-part story, but there are no relationship cliffhangers.
