Don't really remember any of the books because I don't remember ever fully finishing the first book.
All I remember is the cover was beautiful! There was a young girl on it with really pretty eyes. Can't remember the color but it was an unnatural color. I believe it's a Sci-Fi teen series. I remember something about a crystal ball maybe and she had a very unique name that I believe was also the title of the book.
It was early 2000s. I remember being in elementary school when I found it. I'm 21 now. I'm thinking the eyes might have been purple. But could have been a green or blue also. I remember the crystal ball thing that she got it on her birthday or some special day. It's supposed to help her with her future. I honestly didn't read the whole book probably only the first couple chapters but it was so long ago. I just remember the cover is why I got it. The girl on it was so pretty and the cover colors and everything I just wanted to have it.
It's not these books:
The Messenger - Carol Lynch Williams The cover of that book reminds me of the one I'm looking for. The writing might be the exact same or close. The coloring style of it is the same. The difference is the girl. The girl in the one I'm looking for is younger then the girl on this one. Her hair is down and the eyes are of course colored.
Definitely not Alanna or Avielle as answered.
