Great series, fantastic audio. I was very, very impressed with the ballsy way the book ended, until about 10 minutes later (in audio time, probably only a few pages) that remarkable thing was completely undone. It didn't need to happen that way. Sigh. 
 Anyway. I can see this being another Hunger Games-type book, in its general themes of the effects of war on children. But also the effects of colonizing in a new place, of moving, of growing up... there's a lot of discussion fodder here, and a lot to think about. 
 But mainly, the audio performance is awesome.
