I enjoyed this as a whole, especially the way the author worked in the history of tattooing and the West. I liked hearing about the author (and Slade's) opinions of tattoos and why people get them, what they mean at the time and what they come to mean later. While I agree with Karol's comments to some people prior to getting their ink (ex. "don't get a cartoon character, you'll regret it later") I had a bit of a problem with the amused tone she used when telling of some of the off-hand, occasionally insulting comments other artists made while actively doing tattoo work. Sure, try and talk someone out of a bad idea, I'm all for that, but don't be disparaging when it's too late for them to change their mind. IMO, that's just being mean.
I found I could relate to Karol a bit, though she has taken things much more to the extreme than I. I have five tattoos (with plans to get more) and got my first one about 15 years ago. It wasn't as mainstream then so I admit I too have a bit of the same underlying resentment at how popular tattoos have become as Karol seems to have. I also have dated my share of "socially unacceptable" men, though never as extreme (or, thankfully, as dangerous) as the ones she has kept company with. I think the moral that her ex-boyfriend tells is very true ("you knew I was a snake when you picked me up") and is something more women should remember. "Bad boys" can certainly be a lot of fun and get your adrenaline pumping, but the truly bad ones are just that -- bad. I certainly hope that she has stayed away from that type of guy since writing this book, especially since she has a child to be concerned about now.
Arizona isn't quite as much "the West" as Wyoming, but it is definitely different from living back East or out in California. The desert is its own world and I liked reading about Karol's love for her own little world.
All in all, a decent read. Enough history to be interesting but not a dry history lesson, enough personal experience to be unique but not something others cannot relate to on some level or another. (And I, too, laughed at the "nonconformist" tattoo story.)
