I enjoyed this book. 
 At times it felt a little forced, especially the character of Devi, the alien species seem pretty generic to me, and so do the characters of Nova and Ren, and the ending caught me completely by surprise (it felt like there was at least another chapter to go, it didn't feel finished), but it's a first in a series, so I can probably get over that; other than that, I liked it! The plot is interesting, or at least it sure does make me want to read the rest of the series, and so I will. :) 
 All in all, it's a good SF novel, if you're looking for something light yet true to the genre.
