I'm going to skip the usual Good, Bad, and Ugly review on this one. I'll just say that, while this story is very interesting and applies some known future tech with a dose of imagination to "see" the future, it reads like a manual for constructing a series of novels rather than one story, liight on details.
This is not to say you should not read this. I just think that, as a blueprint for a nulti-novel series, this could become a brilliant masterpiece, rather than an above average story.
I cannot say that I've read every story on SOL by Howard Faxon, but perhaps most. Mr. Faxon writes some good stories. Many worthy of a chuckle and laugh or two. Some give pause and provoke an interesting thought or two. But IMO this story is his best - by an order of magnitude!
I found myself nodding my head in agreement more than once. Shaking my head in amazement - why didn't I think of that - more than once. And then, at the end, nodding in agreement with the conclusion.
10-10-10 is my rating.
Story plot: The theory and engineering behind human diaspora.
Technical quality: No notable grammatical oopses.
I've not the educational background to evaluate the technical details to know whether they're even theoretically feasible, but the author has blended them into the story line well enough to make them seem plausible to this layman - and what more can one ask from a SciFi story but plausibility?
You'll enjoy it if you like a good dose of hard SciFi.
