 This is the first Rachel Vincent book I've ever read, and I definitely plan on picking up some of her other series later on. 
 Blood Bound takes place in a world where some people have special powers, those are are special each have a particular talent. Some can track down a person with just a name or a drop of blood, some can jam the signals and prevent people from being tracked, some can travel through shadows, some are human lie detectors, some can create contracts that will literally kill you if you fail to live up to whatever it is you have agreed to, etc. 
 I love urban fantasy, so I am always excited to read about a different world, and with the genre being so crowded now, it is interesting to see a take on a different world without vampires, weres, etc. While the new ideas were interesting, I am going to have to say that I found some of it to be a bit too much. For example (view spoiler)[ in this world, a father, who has never met his child, can mentally decide to assign them a middle name which can then be used to track them - it doesn't matter if the child or the mother or anyone else knows the name, it can just be mentally given. I am willing to believe that a tracker can find someone just through their name (in this world a person's name has a lot of power) but that other part just seemed to be a bit much. (hide spoiler)] 
 Anyway, the title comes from the more important parts of the mythology that the author presents; in this world it is possible to bind a person to the word through oaths. A person can even be bound without their consent so long as someone has access to their blood. Needless to say this creates a very complicated world in which each character is bound to certain contracts/oaths/promises. 
 One interesting aspect to the writing is that the author uses multiple POVs; half the story is told from Liv's POV and the other half from Cam's. Normally I have no problems whatsoever with this technique, I actually really enjoy getting to see action from different perspectives. The nice thing about this book is that despite switching POVs the author did not backtrack and make us reread scenes from a different perspective, the story was always moving forward which was nice. The only problem I had with the switching was that it was not consistent, a change could happen in the middle of a chapter, or we could go a couple of chapters in Liv's POV before switching back to Cam's. I can understand not having an even amount of time for each character, the author would want to put whoever was more involved in the scene on the front line, but it would have been nice if there was some indication when the shifts happened, the way it read to me was a bit disorienting because of the unexpected switches. 
 Overall the book was a lot of fun to read, it was a pretty quick, I was drawn into the characters and the world they inhabited, I was able to guess the surprise about Hadley from a mile away but at least I could also see why the characters in the book couldn't see it, and by the end it left me desperately curious to find out what happens in the next book (too bad for me that the second in the trilogy won't come out until 2012). The book is meant to be part of a series, so of course there is a significant cliffhanger but the main mystery/action plot was wrapped up nicely which makes up for a cliffhanger (I can't stand it when books that are parts of series come out and it takes three books to wrap up one mystery, each book should have its own beginning, middle, and end - whether it is part of a series or not).
