This third volume was the last one I have in this series and frankly, I don't think I will continue after this. While I'm a bit intrigued whether they will at some point be able to communicate with the Gauna and what they would learn from that, I don't think it is worth it continuing the series.
More battles that are hard to follow, interspersed with some seemingly random scenes which do little however to develop the characters further. There's a couple of flashbacks as well, and one of them did confirm some of my suspicions, while another one left me with more questions and less answers still.
Interesting premise, but it didn't really work for me.
