Killer Reign by Eva Chance

This puppet has cut her strings…

I had to do the unthinkable—and now I’ve discovered that every move I’ve made has been part of a villain’s maniacal plan. All this time I believed I’d found my freedom, I’ve still had someone pulling my strings.
Those days are over.
The man who considers himself my master is the worst monster I’ve ever known. My crew and I won’t let him get away with his manipulations or the even more disturbing crimes we uncover.
But no matter how talented we are in our killer skills, we’re just five people up against a crime lord with more connections than I can count. As he pushes us closer and closer to the brink, how much will we lose trying to end his reign?
