It's going to be tough to review this one without giving away some of the surprises in Sinner's Steel, so I'm going to just say that this is a terrific addition to this MC series. Zane and Evie are so good together but they've got some hurdles to jump before they can move on as a couple. Some of those hurdles are their own fears and some are coming from one of the real bad guys in this series, so be prepared for anything to happen! 
 Zane's best buddy Jagger has a good size role in this, as does Arianne and it was great to see these characters from a previous book. 
 This series is in my top 3 MC series that I read faithfully and Sinner's Steel did not disappoint me. It has just the right mix of MC-badness and men that ride the edge of being decent, stand-up guys while partaking in criminal activity for good reasons.
