I've read this series over ten years ago. But I remember it being very good. For the first 18 books. After that the more it lasted the worst it got. I stopped at book 32. These days I wouldn't give it more than 20. 
 Back to the good stuff. I found that Gaia was a good strong, pretty but still flawed character. She was special without being annoying. It's just that once the author stopped looking over the shoulder of the ghost writer. Things went down the drain pretty fast. 
 Last note. The series may be in boxes but I won't be giving them away any time soon. She's a good example of an interesting main character in an interesting premise.
