3.5 Stars. I liked that there was actual progression of the plot and there are still more books to come in the series. I love Owen and Gin together and (view spoiler)[ Finn and Bria (hide spoiler)]. As I mentioned in my comments as I was reading, I was a little irritated by the lack of imagination by the characters when it came to fighting and weapons (view spoiler)[ when Gin goes up against Mab she says she doesn't want a confrontation, just to stab her in the back...so why not shoot her in the head? When the bounty hunters are surrounding Finn and Bria and getting killed everytime one of them steps out of hiding, why are there no Molotov Cocktails? 
 I think it took guts to allow Gin to finally kill Mab; many authors would keep her alive int he background or something since she's The Nemises, but now we can see the aftermath and what Gin does when her purpose is complete. (hide spoiler)]. 
 I really liked that we weren't constantly reminded who the characters were, or that it was at least done a little more subtly. I did notice the overuse of "that much more" especially in fight scenes. I know this sounds like a lot of complaining, but I really do enjoy the characters and the plot; there are just some quirks in the writing that grate on me. I will definitely be reading By a Thread.
