(*) Who was J. Noah Kym? Is the name a pseudonym?
A lot of people seem to think so, though I've never really seen any reason as to why they think that. Purely because he's never written anything else in Trek?
But if it is a pseudonym, my guess is that it's Marco Palmieri. Given that Fragments & Omens set into motion a lot of the continuing arc plot of that section of the book series, and Marco was editor of the series at the time, I could see him wanting to take a personal hand in getting it right. But also because he was editor, it would be a conflict of interest for him to do so, hence the pseudonym.
We know that pseudonyms are hardly unheard of in Trek Lit (*cough* Mack *cough*), and that Marco is a perfectly capable writer as well, since he contributed to the Vanguard series as an author under his own name once he was no longer editor. So it's possible.
But that's all wild speculation based on no hard evidence whatsoever and could very well be completely wrong. J Noah Kym may entirely possibly be a real person for all I know.
On topic re Paradigm, I also like the subtle use of varying cultures on Andor - the modern-city life of Zhevra versus the traditionalist farmers-and-artists life of Thelasa-vei for example. As for comparing it to screen-canon depictions of Andor in Enterprise, I think it feeds well into my general theory that when humans first met Andorians, the latter were in the tail end of an ice age. With 200 years of climate change and advanced technologies, they now live in much warmer temperatures. But the consequence is a certain meteorological unpredictability, such as the flash-floods.
