I was struggling to decide whether to give this 4 or 5 stars, but ultimately I decided on 5. I know if I had read this closer to the time read the previous books there would have been no question. I wasn't so attached to the characters anymore because it's been forever since I read the first two book and I think that is understandable. I'm still pretty much basing the rating on enjoyment (as if I didn't always do that) and even though there were things I didn't like in this book I still really enjoyed it. 
 This book had so many elements that I like: great main characters, action, science fiction, mystery, romance etc. It was great to see Amy and Elder discussing and making decisions together and collecting pieces to see what's really going on. I loved learning more and more and figuring it all out even though it was pretty easy to guess who the real enemy is. *Haymitch voice* (view spoiler)[This once again showed how ruthless and careless humans can be. And the sad thing? It didn't surprise me at all. (hide spoiler)] 
 The one thing that irritated me was Amy's dad (and maybe some other "Earthborns"). That attitude! First he didn't like Elder. He didn't like the "shipborns" and he treated them like he and the Earthborns were better than them. Then all he wanted was blood. To kill all the aliens. Basically every human thought of Centauri-Earth as their planet and thought they could do anything without consequences. But no, it's not their world, it's already inhabited. 
 Yes, I do like conflict. Otherwise I couldn't give this five stars! :D But I really liked how everything turned out in the end, I think it was a good way to end this trilogy.
