It was awful. The story, the characters, the plot line. Flavia Bujor cannot write worth a darn.
Let's diagnose her characters, shall we?
Jade: Pretty much the only interesting character in the whole book, has a few sue-ish tendencies but at least her bratty, spitfire personality makes up for most of it
Opal: Good Lord, I hated this girl. Especially her crush on Adrien, she was the main reason I hated this book.
Amber: A stock character, not entirely too bad, but she really should have stayed single.
Moving on the the plot and the story:
When I started this book I grazed through almost all of the chapters in which Opal had a major role. I understood most of it Until the end. Like WHAT THE HELL. And, enough to say, I really wanted to punch both Elyador and Adrien. Shallow Love Interest much? Shallow characters in general. The best (and I used this term loosely) was the meeting with Oonagh, she literally stole the scene.
Final Verdict: This is like Twilight, but slightly better (I use that term even more loosely).
