I am an engineer too, and have written a hard science fiction Novel: https://www.amazon.com/dp/B0GFTDY4ZL

Given that there are so few of us writing hard sci-fi, I would like to read your novelette. Where is it available?

Hey, thanks! mine is at https://www.amazon.com/dp/B0GQ8B1SN7 The Kindle book is free right now.

Enjoyed it very much! Self contained though it is, it would make an excellent opening part to a First Contact story. I've left a review on Amazon. I can offer other comments directly to you, but I'll leave that up to you.

Thank you for the review comments!
