July Challenge - Sci-fi

A challenge with my favourite subject to write on. Whether I'm good at it is a matter of debate. That said, I entered a story in this challenge that was written a few years ago as flash fiction and with feedback from multiple readers, I managed to expand it to a short story (~7000 words): https://novelo.com/story/631/

If you happen to read it, please share your feedback/comments. Thank you.
