Acrimony by Morgan Kelley

Payback is his goal.
Someone has his child, and Jagger Armstrong isn’t playing a game with her life. He’s been given the address, and told to head there. Oh, he is, all right. His plan is to raise all kinds of hell in the French Quarter until he gets his child back.
Failure is not an option.
Only, when he gets there, he sees that this is a desperate situation, and he’s stuck between a rock and a hard place. Mainly, between retiring with his daughter and the woman he’s madly in love with, or staying to help a bunch of strangers—some Marines and some ex-Feds—save a city on the brink of self-destruction.
It’s one hell of a choice.
And he’s not the only one with one to make…

Maura Gaines-Mars has had her life turned upside down, and she’s so damn lost. While she knows the path that she’s supposed to be on, there’s something about the city that has made her feel…at home. What she does know is that women are being sold into a sex ring, and that’s unacceptable to her.
Period.
FBI.
HUNTERS.
MERCENARIES…
To her, right is right, and she’s still a Marine until the end.
Will New Orleans be the place where they say goodbye after years of having each other’s backs? Or will this be a brand new adventure for the son of a mob man, and a badass Marine?
In New Orleans, the City of Second Chances, one can never tell…
Acrimony is on the menu, and it’s going to be one hell of a fight.
