Sometimes I think there are ideas that, for lack of a better word, haunt us. All of us. The preoccupations of humanity, or some other grand-sounding phrase. Frost wrote of a road not take. L'Engle wrote about might-have-beens. Choices and their consequences.
Monica Byrne's "Nine Bodies of Water" engages with that idea as well, and makes clear that an alternate name for choice is sacrifice. It's a powerful story. "Nine Bodies of Water" was originally published in 2010 in Fantasy Magazine.
