I feel like I have been holding my breath for a loooong time. Have you ever been exhausted after the excitement of a book just as if you were one of the characters? I feel that way... like I just run a marathon. 
 There is so much action on this book that it feels it will never end (I think that is exactly the point). Alien ships are coming one after the other to claim the planet for reasons we discover later in the book. There is one scene that stuck in my mind because it reflected exactly what I was thinking: Zubiri crying when yet another ship is discovered heading for the planet. I would have done the same, cry and wish it to stop. 
 I was exhausted on the characters behalf and sick of war. 
 All questions are answered. It seemed impossible in the first book, but the author finally got us there, leaving no loose ends. Well, details about the rebellion are not explained, but it is enough to understand what happened. 
 Now the bad. It is time for the love-triangle rant: (view spoiler)[ Why does it feel like the love-triangle still exists despite O'Malley being dead?! (hide spoiler)] And the worst thing: It was all for nothing. (view spoiler)[Despite what other people think, I understand Mattie's decision, but couldn't it have been Bishop merging with his progenitor instead of Victor? If Old Bishop would have taken the place of Old Victor, it would have been PERFECT. I also don't mind Em merging with Matilda, it seemed the right way to go with the story. (hide spoiler)] 
 Great series! I was in need of something different. Now what do I read?
