As much as I like Kelly Fox as an author, this book doesnt't really work for me.
That's why I dnf-ef around 50%, and that's the reason for the low rating.
Let me try to explain why.
It's the story of Nacho and Bram. They met sometime back, when Nacho was in prison and Bram was his doctor/psychiatrist. During that time, they developed some kind of an D/s or rather daddy/boy ish relationship. It's hard to pinpoint because they seem to slip into it, without actually talking about it. Bram calls Nacho by his real name, Ignacio, and Nacho calls Bram Dr. Barlow, and while they don't actually touch, it's clear to both of them that the dynamics are arousing for them both.
A while (a year? more?) later, Nacho works for Justin and Jason's fencing business (just look at the previous books/series, they're all somehow interconnected when it comes to the town all the gay cowboys and their partners live in -I swear, it's THE gayest area ever known to mankind, even if you do have the odd homophobe popping in and out).
Bram moves there with his brother, and works as a therapist. There, meeting up with Bram again, and they start with their previous dynamics.
Again, not really talking about it. At least for a while, until things get physical between them.
That's the point where they start talking about it. Up until that very point, Nacho didn't even know about BDSM/power play relationships.
And while I appreciate bringing in that "taboo" aspect about doctor/patient relationships, I felt very uncomfortable about it here, probably because the doctor in question was a psychiatrist. The switch between Bram the counselor who listens to Nacho's mental issues, Bram the "Dr. Barlow"/power play/kink person and Bram the boyfriend (of sorts) felt too smooth, without any clear boundaries. Mind you, I don't have any issues reading about almost any kind of kink, but it somehow feels unsafe here, because there are no real rules in place, no safe words, nothing.
On top of that, the vigilante aspect of this series feels off. While - again - I appreciate the topic, and the fact that it's treated in a way focuses on the rescues and on the positive prospects, it feels like dipping your toes in shallow, murky water and then shrugging it off and focusing on something else.
Anyway. No more analysis. It didn't work for me, despite the pretty good narration, and I don't think I'll continue with this series.
