Can I just start by saying that I feel like the only person who doesn't like the cover? I mean, the background is nice, but the guy just creeps me out a little bit... Sorry!
Yay, its in first person! I found Obsidian very easy to get into and i immediately loved Katy because she always stood up for herself and was hilarious at the same time - and she blogs about books! SHE UNDERSTANDS!
Enter Daemon. Whenever I was reading Daemon`s conversations, I ended up doing one of three things: cringing, laughing or wanting to punch him in the face. I know that the whole point of Daemon was that he was supposed to be a "bad boy" type guy but... gah! He could be so annoying (yet funny), and treated Katy like crap most of the time!
I was starting to hate Daemon, but he redeemed himself at the end of the book. I really loved the second half of the book, as there was a lot more action, and the "Katy and Daemon" ending was brilliant...
I guess Obsidian is supposed to be science fiction, what with it being about aliens and all, but i found that the main focus of the book was the romance between Katy and Daemon. So if you don't like romance, then this book probably isn't for you.
