I had a feeling that I was going to get to the end of this story and kick myself for not having read the series sooner. 
 Great mix of action, drama and romance. I really like the fact that these guys are flawed and have their own demons to work through, and that they're both badass in their own right. Interesting plot and characters which kept me reading and I loved the (view spoiler)[showdown at the end with the bad guy (hide spoiler)]. There were a couple of instances of 'huh did I miss something' in places but it didn't detract from the story and I figured I might have indeed missed something. 
 Will have to read more of these guys now, you've got me hooked, Lou.
