Morally grey heroines in romance novels who could rule the world if they wanted to

I could probably name you thirty romances featuring morally grey heroes off the top of my head. But what about morally grey heroines? That's not as easy as you might think. But because I'm not one to gatekeep, here are the ones I came up with...you know...if you're into that kind of thing:  

Criminals Need Love Too by Isabel Jordan

The Mindf#ck series by ST Abby

Black Heart by Lynn Raye Harris

Ghost by Janie Crouch

Ain't She Sweet by Susan Elizabeth Phillips

The Perfect Crimes of Marian Hayes by Cat Sebastian

Faking It by Jennifer Crusie

Double Exposure by Rien Gray

Butcher & Blackbird by Brynne Weaver

Kiss of a Demon King by Kresley Cole

But those are just MY picks. What say y'all? Anything you'd like to add? Let me know in the comments!
