I'm kind of divided about this story. I attempted to read it once before (2010-ish), but I didn't I get more than half or 2/3 of the way through. That is not a reflection of the novel itself (I just get easily distract by shiny things). 
 Anyway...I am now (some would say *finally* reading Cut & Run, and a little birdie has informed me Julian Cross and Cameron Jacob make an appearance in Armed & Dangerous (among other later volumes), so I thought I'd give it another go, because I'm a little OCD like that: 
 Alright, I liked the characters (Julian, Cameron, Preston, Blake, dogs *and* cats). I wasn't blown away by any of them (though I really liked Preston, but that might have been because he reminded me a little of someone else I'm quite enamoured of). 
 It is a good novel, it has a well-paced plot. If anything detracted from my enjoyment, it was the fact that I read it smack in the middle of Cut & Run. And it's not so much that the action and excite for those novels is higher (though it is) but that the relationship of the two main characters is different (it has more time to develop, but them, by the very nature of being who they are and having different personalities, have a different story). 
 Julian and Cameron are different people and have a much more low key kind of story. Plus there's the fact that for much of the story, we see the events as they unfold from Cameron's POV, and Cameron doesn't really know who Julian is, what his life is like, etc... 
 We have a case of opposite (the assassin and the normal, everyday guy). It's a little more complicated than that, but as we don't see things from Julian'sperspective we can't always see that. 
 Still, it's a good story, and I won't mind seeing them in Ty and Zane's universe (though I'm having all sorts of visual's about clashing personalities and how misunderstandings might ensue) 
 I guess we'll have to see how that shakes out...
