I like the concept of Legend. However, I just get so tired of these futuristic dystopian novels with "strong" female leads, that can only focus on their love interest and the shape of said love interest's lips. I also found the lack of explanation of WHY there is a republic, and WHY the USA is split, to be REALLY frustrating. THere were great ideas, but they weren't fleshed out. Probably because June and Day were to focused on how beautiful they find each other. 
 All that being said, I liked Legend. I've been told that the story improves and that there is more in the way of explanation and development. I am looking forwards to seeing that happen.
