This is one of my most favorite on-going Urban Fantasies at book number 16. The excitement is always there when I hear that there is another one due for release and I nearly always devour it in one sitting. I think I'm especially fond of the later books as they have a lot more backstory in them. This occurs through Gin's flashbacks. This is a series that must be read in order to appreciate the subtle changes in Gin. The growth that she has made from a vicious assassin to a more caring sister and lover (though still an assassin) has been fun to watch. It's rather like peeling back the layers on an onion. I do wish that there was a bit more involvement with Owen in the story-line rather than just a helping hand in Gin's latest escapade. I know that the books where Finn was more of a major character than a secondary one were much more interesting. If you've not read any of this series and love action packed Urban Fantasy, you are really missing the ride of a life time. As a lover of series binge reading or TV watching, I almost wish I had this series in front of me to indulge in.
