Amazing. I found the civilization on the terraformed planet to be completely fascinating. I haven’t read or watched a lot of sci-fi, but I remember stories where the humans were the heroes and had to fight alien invaders that would come and try to annihilate them. In this novel it’s pretty much the opposite: the humans are the invaders, and I was rooting for the "other" civilization. The end was also very satisfyingly: somehow surprising, yet consistent with what happened before.
