Re: TNG: The Stuff of Dreams by James Swallow Review Thread (Spoilers!
I agree with your point (it's always nice to have unexplained things at the edge of the map), but it has actually been expained before(albeit in a humourous & possibly-just-to-get-a-rise way) in the q continuum trilogy.
Something that the story didn't address was the actual origin of the Nexus. And I'm glad for this. I think it's an important fact of life that there are some mysteries in the universe that can never be answered; in terms of fiction, this means there have to be elements of the narrative which are never explained, and, indeed, were never meant to be explained. Sometimes I think Trek writers (TV and prose) are a touch too eager to explain things that I had previously felt were not meant to be explained. (Damned if I can think of an example; I was thinking of one just the other day, too. So I could be talking out of my rear here.) So I appreciated James Swallow's approach.
