For a good while I wasn't sure I was going to like this book. It was pretty awkward that the main character was a book blogger and I felt ten different kinds of self-conscious being a book blogger myself, feeling as though someone had read my diary or something and my shameful secrets were exposed to the world - you know that feeling. However, Katy is such an earnest, sincere character that despite my efforts to remain unaffected and a little cool towards her, I couldn't help but totally throw my lot in with her infectious enthusiasm and sassy attitude. Armentrout's greatest strength lies in her characterizations. She creates characters who are easy to empathize with, fun to listen to and who are dynamic. The dialogue is pretty awesome and there are many moments in the novel when you won't be able to help laughing out loud. The plot is also something sort of new. I mean, it has the typical elements, bad guys, forbidden love etc, but it is sort of refreshing in that these are not paranormal creatures but aliens. I'm all for aliens. Though, honestly, I don't like the name Daemon. It's a bit too overused. How about Jared? Or um, Bartholomew. (That's a mouthful.) Daemon was an ass, no really, a serious asshole who treated Katy like crap at times and I should have hated him and I probably would have hated him had Katy not given back as good as she got. She wasn't written as a doormat and she didn't need the reader feeling outraged on her behalf. She felt outraged on her behalf which made a world of difference in the way Daemon was ultimately received by the readers. No matter how much effort he exerts to act as The Man, Katy refuses to let him become the alpha male he wants to be. I loved that. The plot, pacing and writing complement each other perfectly. Obsidian succeeds in achieving what it sets out to do: entertain. If you go in expecting a tremendous ride and not something substantial, you will come away with a grin and a wish for the next book in the series.
