I saw the review. Thank you so very much!
Not similar as in a Hitwoman, but I
guarantee you'll enjoy it as much as what you've read thus far. This's about an underground fighter who leaves the game, only to be taunted by ghosts of fights past, and finds out no matter how far one flees he can't get away. It takes place in northwest Montana and involves heavy fists, a 3 screw .45 Ruger, and a Winchester LW in .45-70! Also a damsel in distress, although I think we can agree there wasn't one in both of the ones you've read.
Edited to mention, I think you'll enjoy the third in the Hitwoman series and will understand its title.
Sanctioned Hitwoman!
