I was enjoying the thought experiment. I didn't like that it ended so abruptly-- the story was not finished. I admired the agent, and the character of the geneticist. I wanted her to reach a lab .
I liked that it addressed trans issues, and that gender is on a spectrum., for example the women with Y chromosomes who also died that day.
I didn't like the character of Roxanne-- I wanted her to be less Heart-of-Darkness and more strong feminist. I wanted them to continue encountering a variety of communities.
