I wasn't too happy with the similarities between Obsidian and Twilight while reading it. While I like almost everything about this one better, the fact that it felt like I had read it before overshadowed everything else. I did like the characters and the writing, but I could only give Obsidian three stars. And even though it wasn't a favorite of mine, I couldn't resist the pull of Onyx. I had to find out what happened. And I'm so glad I did!
