A kick butt start to an awesome new series! Patricia Briggs has a fast and furious writing style. This is a shorter book than some might be used to but there isn't a word wasted and a not a moment I didn't enjoy. 
 There is a lot of urban fantasy out there these days and I believe this by far is some of the best executed beginnings of a series I've read to date. The details for a rich world of 'Other' within our own mundane world are delivered so well that they aren't overwhelming. There is nothing worse than when an author does an information dump on the reader - and while Briggs gives you a lot of info it never feels as if it's too much. 
 Mercy is a great lead, a character that you can really get behind and get attached to. She's tuff but vulnerable and sassy as hell. I highly recommend this series to any urban fantasy fans that have a taste for werewolves, shapeshifters, vampires and few.
