I'm a little embarassed, because I thought this was a trilogy, only to tell myself in the last few chapters of the book "Boy, the auhor's gonna have to hurry if he wants to pack a whole epic alien versus humanity fight ending in those last few pages!". Well apparently there are going to be more books. Which is great, because I enjoy this series so much! 
 Humanity seems to finally have realised that everyone has to work together against those sturdy giants that kill colonies off like humans destroy anthills with a hose. I think the ants analogy is even used in the book a few times. Or was it cockroaches? 
 Anyway, we get to meet plenty new and colorful characters and the author tries his best not to stereotype any of them and I think he did a pretty good job with it. 
 Of course the little love story that has appeared at some times in the book continues, but I'm not going to spoil too much for you. Just let me say that I value the fact that Marko Kloos doesn't try to make a big deal out of it, but rather mentions it casually from time to time, which gives the story some extra layers but doesn't take away from the main events. 
 What I miss a little is the evil, the disgusting, the intrigues. It seems from time to time that all characters are happy to help or throw their lives away for the sake of basically anything and there isn't really anyone that's on the opposite site of the spectrum. Even the Lankies seemed like big, very weird looking and puzzled dogs that run around and kill everything because they don't know any better? I mean I like the tone of the book very much but sometimes it felt... I don't know - too puffy? I mean sure, there are villains in some scenarios, I'm talking about the whole Luna affair, but it seems to be over quite quick again. This doesn't mean I didn't enjoy it, I just think it would have added more colors to the canvas, but that's my personal opinion. 
 So without prolonging the review much further I'm just going to say that this book had very interesting passages and turns. I'm looking forward to #4 and am very excited to hopefully finally learn more about the Lankies.
