This is a very average 2.5. There was way too much not explained for there to be a healthy amount of curiosity.

Quinn and Lexa are artifical and they're treated as if they're robots but they have human lungs, bones, brains and organs, plus they still need to eat so I'm confused exactly what makes them "artificial." It reads as if they're just genetically modified, lab-born children but they're talked about as if they're robots. Even the slurs and insults are robot-based.

There was also a switch in POV in the epilogue to first person instead of the third person the rest of the book was written in and it was odd and an unnatural switch.

This is a prequel short story, but it didn't leave me interested in the main series at all.
