Wow - it feels like I've been waiting forever to get my hands on this book, and once I did, I did NOT want it to end! I think I actually tried to slow down my reading through the last 20% of the story just to make the fun last. This was so totally worth the long wait for its release. That said, the story started a little bit slow for me, but I was expecting that, actually, given the necessary world-building and character introductions and knowing how thorough the Ilona Andrews writing team is with that element of the story. Once it got going, though, this book was a steamroller of action, suspense, magic, and mayhem and I enjoyed it a lot. 
 Nevada and Mad Rogan are great characters. I loved them - both of them. I especially loved the direction that Rogan's character took. He's definitely not what I would call a Good Guy, and he's too morally ambiguous to really be a Bad Boy. No, Mad Rogan is definitely a Bad Man...in ways that are delicious when they're not disturbing. I loved him. 
 Together, Neva and Rogan have the sort of chemistry that could, eventually, turn them into as awesome a couple as Kate and Curran, if an arc of romantic elements head in that direction, and that's a big plus for me. In fact, there were several scenes that reminded me of some of the greatest Kate/Curran moments from the first couple of books of the Kate Daniels series. Nevada and Mad Rogan aren't carbon copies of Kate and Curran, but there is definitely a...similarity in tone and emotional temperature to that legendary couple's initial introduction and subsequent interpersonal struggle. 
 All I know is it gave me plenty of warm fuzzies. 
 In short, great world...that was just fresh enough to feel unique to the world in the Kate Daniels series but with similar themes in character conscience and a taste or two of familiarity of personality. For me, Nevada's narration had a tone that was a bit too close to Kate Daniels to allow for the originality of character that I was hoping for (though no one can beat Kate when it comes to self-deprecating snark and sarcasm), and Mad Rogan shares a certain level of arrogant confidence and royalty-level entitlement as Curran (it wouldn't have surprised me at all to have Neva turn to Mad and sarcastically call him Your Furriness). 
 That isn't really a bad thing - there's a reason the Kate and Curran relationship works so well for me through the arc of the series - but I think I would have enjoyed a bit more separation and uniqueness in the more subtle and internal elements of both Nevada and Rogan. 
 Oh, don't get me wrong - I'll DEFINITELY take what I can get, regardless, because this book rocked. And I'm totally bummed that it went by so fast. Between the Kate Daniels series and this one, the wait for the next Ilona Andrews endeavor may just kill me.
