Tower of Glass Kindle Edition

3.9 3.9 out of 5 stars 167 ratings

From the Hugo and Nebula Award–winning author: “High adventure, considerable tension, and—most important—social consciousness” (Harlan Ellison).

Simeon Krug is the king of the universe. A self-made man, he is the Bill Gates of the era, having built a megacommercial empire on the backs of his products: androids, genetically engineered human slaves. Having amassed incredible wealth, his next major goal is to communicate with aliens living in an uninhabitable world, sending a mysterious signal. This requires building a mile high tower in the arctic tundra.

The androids want civil equality with humans, but are divided on the best means to the goal—political agitation or religious devotion to Krug, their creator. And Krug’s son, Manuel, is reluctant to step into his role as heir to his father’s empire.

This is my first Silverberg novel, and it was quite enjoyable. On occasion, some of the style became a little too clogged for my taste, but in all, it worked well. There is a forward explaining some of the process he went through creating this story, and I believe that was an excellent move. Without that insight, I’d have been a lot more impatient when the prose became quite repetitive.

I would call this a light story. It’s a far cry from the hard-science and military SciFi I’ve been reading. A welcome relief. I do have one criticism of the Kindle presentation: There are far too many typos throughout the book. It looks like the original, printed version was scanned with a cheap scanner, then simply uploaded. No proofing involved. Randomly and throughout, ‘I’ is displayed as the numeral one; letters are missing from words; the shows up as Dh; the list is fairly long. Since the story and writing are absolutely fantastic, the typos were really rather jarring.

A real classic of science fiction. A must read. Some editing problems with this edition. It appear to be scanned from a print edition and contains some scanning errors. But this does not much detract from the quality.

I am conflicted as I write this review. I have just read the kindle version (no longer available on Amazon I gather). The digital version appeared to have few, if any, defects (which is in STARK contrast to the many other offerings on Kindle I have read).

This is an interesting book, on an interesting topic. However, it is not "my" kind of sci-fi, which centers more on the awe of discovery. This book, clearly focused inwards, as opposed to outer space and awe of discovery, was very good, but just never really moved me. To be honest, I only completed it because I am on a plan to complete reading all of the Hugo and Nebula award nominees/winners.

I mention all of this, as your mileage may vary. Well written and interesting subject matter. Just never connected for me. But, if the subjects of slavery, individual right, caste disparities, and how we as a race view/deal with them, are of interest to you then this could be the book for you.

Robert Silverberg's Tower of Glass envisions a future where artificial humans are produced (through some undefined genetic engineering steps; keeping in mind that this was the pre-cloning days for science). This led to a 2nd class, property status for the "vat" borne (as distinct from womb borne) with a further subdivision in terms of intellectual capacity with alphas, betas, and gammas. As their numbers grew, a quasi-religion among the vat-borne developed worshiping their creator (the richest man in the world as a result of his business in artificial humans) as well as a nascent political movement working for full citizenship. Against this backdrop, the "creator" is working on a project, the tower of glass, to communicate with an alien intelligence that has been beaming inscrutable messages to Earth.

Silverberg utilizes the recently (at the time) "cracking" of the genetic code to posit the possibility of building a designer human from which all the political, sociological, and philosophical angles evolve. At the same time, he injects simple, but undeniable transmissions from an alien intelligence, but without meaning as the mode of first contact and adds the use of exotic matter to create the potential for instantaneous communications. Finally, he crafts the feasibility of exchanging consciousness with another human being as a form of entertainment.

Overall, this was an ambitious and forward thinking conceptual piece for its time.

The central character in this novel,Krug,wants his androids to build him a tower of glass. That's the set up that explores issues of religion,slavery and the treatment of sentient beings.
Reviewed in the United States on July 25, 2020
I've read Tower of Glass several times over the decades. Silverberg is one of the old time Sci Fi masters. This was the first time that I read the book as a fully devoted follower of Jesus Christ, so it hit me in a far different way than it did as a youngster, still struggling with my faith. In my earlier naivity, I missed that Silverberg was most likely an atheist, and making light of the Christian faith. The story is very well written, but the betrayal the protagonists all feel attacks not only the believer, but the deity of the lead protagonist as well. Although I enjoyed the read once again, it was deeply disturbing in a different manner than the author no doubt intended. It did not in any way shake my faith, but it made me sad to draw understanding of the hopelessness that those that do not have faith experience.

Lost my 1st Edition copy. Purchased this one to replace it. If you are into Science Fiction you should like this book.
Reviewed in the United States on June 7, 2020
Seldom have I not immensely enjoyed a novel by the Master, seldom have I not been fully immersed in his world building, his character building, his tension building and his climax building.

All the elements are here, in Tower of Glass, but somehow, the novel, like the obelisk it describes, seems to have missed a balance point. Perhaps Robert Silverberg could not make his mind up about whether this should be a first contact novel or an androids coming of age one.

Or perhaps, he was running on creative fumes back in an era where he almost gave the googol a new definition, with the immense number of words he was producing. This does not mean that Tower of Glass does not have its trademark Silverberg moments – and actually a walk in Stockholm’s (of all places) android ghetto will satisfy any reader.

But, frankly speaking, it is not really enough, as the whole novel feels rather scratching the surface of things. Tower of Glass is crème but not de la crème. 3 stars.

5.0 out of 5 stars Just great
Reviewed in the United Kingdom on August 22, 2011
This is the book that lost out when Larry Niven won a Hugo and a Nebula for  Ringworld , possibly the worst Hugo-winning novel I've read (while I'm griping,  A Case Of Conscience  isn't all it's cracked up to be, either). The worst part about being beaten by the most over-rated Hugo winner of all time? Well, both books open with a character hopping through a teleporter across the earth, but Silverberg GOT THE TIME ZONE CHANGES RIGHT and didn't have to do a second edition with the high school math corrected.

So while Ringworld is full of leery nudity, Thundercats and dopey tripods and no plot of any real worth, Tower of Glass opts instead for story and characterisation. It's an operatic tragedy with timeless themes about the relationship of master and slave and the siren call of destiny; it's probably the defining Silverberg book. Although plainly inspired by the civil rights struggles in 20th century America, the book still feels fresh, because it's about division of society and the disconnection of the super-rich from everyday reality. The writing is bold and leaps out of the page with unbridled enthusiasm. Silverberg reportedly complains that the book was butchered by its editor, and while, with retrospect, this is perhaps detectable in the pacing, I wouldn't say my enjoyment was harmed.

Ignore my whining about how grievously this was pipped for an award and just buy the book. If you like classic sci-fi, this is a great mix of the Golden Age and the New Wave, it's the quintessential Silverberg novel (as you'll see from my reviews, I should know: I've read a whole lot of them) and it's just a brilliant piece of escapist fun. Enjoy. ...And if you see Larry Niven, punch him in the chest.

OK, don't do that.
