I read this some considerable time ago and barely remember it, which is what is now coloring my rating, because if it had been more entertaining than it evidently was, I'd have finished out the series, but I have no interest in ever reading it again or getting back into these stories at all.
There is a series of four: Tech-Heaven, The Bohr Maker, Deception Well, and Vast and they're only loosely connected, although I believe a couple of them are more sequential and connected than the rest. I never did read the first one and cannot summon up any interest in doing so now.
This story, named after the planet where it takes place, is set in a community which lives on the side of a space elevator. Why, I do not recall, but they are trapped there. How they survive is sketchy. The planet below is supposedly infested with nanotech that is commonly believed harmful, so no one is allowed down there, but even though there are rebels who wish to be set loose down there, the authorities won't allow it. There's no reason at all given as to why they're not simply allowed to go. Naturally they do go down there eventually, but I can't for the life of me recall what happened, which should speak volumes about how uninteresting this was.
Nor is there any info as to why this high-tech society doesn't have robots - a common omission is far too many sci-fi stories. Those robots could have been sent down there to probe the surface and see if the problem was A, as bad as it was supposed and B, getting better or worse. It seems to me that nanotech has a lifespan and maybe all the tech is dead on the surface now. No one seems remotely curious to find out what the status is! That's not authentic and it's a common problem with this sort of dystopic novel because the author stupidly seems to treat everyone as though they all believe the same things and behave the same way - there never are any rebels or conspiracy theorists, or adventurers, or whatever. It's not realistic.
The novel must have seemed interesting enough at the time, but reflecting on it now, it seems silly. There is a main character named Lot who is the son of a guy named Jupiter Apolinario, which I'm sorry but is just plain stupid as names go, to say nothing of pretentious. Earlier, he led a group of followers down the planet and they were never heard from again. Just like his father, Lot is considered a potentially inspiring leader, but as a character, he never inspired me! After all of his suffering, maybe he should be consider a Job Lot?!
We're told in the book blurb that on Deception Well, "a razor-thin line divides bliss from damnation" but if they have no idea what's going on down on the surface, and have never investigated it, how can they possible know this? Again, stupid. Like I said, I did read this once, but I recall nothing of it and have zero interest in starting it again (I know 'cause I tried!), so in hindsight I cannot rate this a worthy read.
