Bloodchild and Other Stories

 A rather dark short story about the painful compromises humans must make to survive in an alien society ruled by the Tlics.
I didn't notice the “horror” tag before reading it, and generally horror is not my cup of tea, but it's a thought-provoking tale of a single, very Alien event that uses gore to illustrate the social struggle between two races who want to survive.
The only puzzling note comes from an afterword by the author, who says she couldn't understand how some readers thought humans were enslaved in the story. I'm one of those readers, and I really believe that the humans only had a choice between being treated like animals or being forced by powerful political and social norms to become reproductive vessels for the Tlics. So I think my interpretation of the story made it even darker than the author intended.
