Prodigy is just as fast paced as Legend was. I really enjoyed it and we finally got the explanation of how the Republic got formed and what happened with the water. There was one thing that happened at the end that I didn't care for at all. I'm not sure how Lu is going to deal with it in the next book but I think it makes things unnecessarily complicated. 
 June is seriously kick ass and I appreciate the fact that Day recognizes that he doesn't need to be her knight in shining armor. Tess is going through a jealous phase. I may not have cared much for Keade in Legend but she was pretty awesome in Prodigy. 
 It was kind of easy to see who the good guys and bad guys were despite the fact that Lu had them all over the place. It didn't take away from the enjoyment, it just wasn't too surprising (You can't trust someone playing both sides, right?) 
 Thomas is really only in the beginning of the book and I hate him even more. Seriously I just wanted to punch him in the face. 
 I know I mentioned in Legend, but it irritates me that Day and June are 15. They do not in any way shape or form behave like 15 year olds. Luckily their age is not brought up as often as it was in Legend so it's easy to forget their age.
