I am SO gutted that Liliya is dead... I accidentally read a hint of it in the previews and went into such a heavy denial about it that I completely forgot about the spoilerish hint. I remembered much later into the book and was sort of mourning every Liliya chapter I came across, thinking "this is the last" So seeing it happen was quite emotional as f**k for me. I never thought I could care for a book character so much. She truly lived as an android and died as a human being.
I also felt for Yaquita's death, it wasn't shown but just hearing how the Xenomorphs took her apart made me feel bad for her. But at least she died fighting, and a good fight at that according to Maloney.
I am glad that my two other favourite characters, isa Palant and Hashori of the Widow Clan survived! Palant and the surviving Marines and Indies as well as the Tanns all go with the Yautja and away from humanity. To an unknown and exciting future.
One of my other favourite characters has an uncertain fate, we know two Yautja died from the explosion caused by Liliya's sacrifice, but we don't know which ones. And it is not stated if Elder Kalakta survives... I think there's a good chance he does live, because if he died, maybe that would have been mentioned, he was revered by the other Yautja including Hashori.
Humanity has been driven back centuries due to the destruction of all the Dropholes. Plus the Yautja took the remains of the Rage ships from Sol and probably elsewhere, denying humanity the technological treasures and taking it for themselves, sort of understandable as the Predators would rather have first dibs on high tech to stay ahead of prey. Hicks, you're right that this does feel like it drove humanity back to the Alien/S/3 era, I was thinking the same after finishing the book. Say hello to all the rusty Nostromos again!
I liked the Yautja drophole in their asteroid habitat, a sort of sun-like, almost arcane technology... almost everything about their tech was arcane, the fading doorways, the fluid materials that can form chairs and food replicators or computers as well as ship controls etc. They are deceptively advanced, possibly the most advanced interpretations of the Predators so far.
Still far ahead of 2692 AD humanity.
