I think I'm going 3.5 stars on this one. Definitely different, I haven't read too much in the sci-fi genre, but I did like this. There were times when I just wanted to scream, though...I have a hard time knowing stuff and the characters not sharing with each other like I think they should :)
I liked our characters, Mella was a good lead female, not overly whiny or stupid or irritating, though admittedly super naive and innocent. She had my sympathy and I felt for her.
I wanted to knock Dain over the head a few times...but he usually got me over that pretty quick ;)
Overall, I enjoyed and would recommend to fans of the genre.
