K, first off, "Bloodchild" = creepy and not to be read right before going to bed, especially if one is particularly phobic about personal invasion by insects to begin with. Personal nausea aside, though, the contrast between assimilating a species into one's own, and using the Other as purely breeding ground is fascinating. "Bloodchild" made "Lilith's Brood" sit far more easily with me.

Ooloi--when I first saw the word, it looked very familiar, but I've never read anything by Butler before, and poking around on the web, she's the only one who's meant to use the word.
