Once again, just my thoughts and impressions.
To paraphrase Montgomery Burns: "I don't know about Literature, but I know what I hate. And I didn't hate this."
Why not? It was enjoyable. It felt too short. I just got into it, and bam! It was over. I want to read more. (Actually, I thought the file had been truncated, and had to check my mail just to see if it was all there.)
It was interesting. The powers, the looming death, hints of rules (no two titans at same time), the social customs (pillars to hide atop, two couples can't use same place), etc. I was intrigued, and wanted to learn more.
The characters felt like real people, and their dialogue wasn't forced or stilted. Also, the alien culture felt like a real one ("Feeder's teeth", etc.)
I swear to god, Cumo, If you kill me while were having sex
That's a great line. Seriously, just a killer line. (No pun intended.)
I learned from reading it, from how the exposition was woven in between interaction and dialogue.
And after reading it, I was a little jealous.
Couple of criticisms: The prologue felt a little awkward in places. I think you were going for stilted, to underline the fact that it, whatever it is, isn't human, but it was too stilted in places.
The third sentence of Chapter One ("Oh, every once and a while") needs to be rewritten, it's confusing. Actually, there are a few sentences that can be line edited. Few as in three or four.
I wouldn't cut the prologue. I thought it worked.
Enjoyed it, looking forward to reading more.
