Simeon Krug has a vision - and the vast wealth necessary to turn dream into reality. What he wishes is to communicate with the stars, to answer signals from deep space. The colossal tower he's constructing for this purpose soars above the Arctic tundra, and the seemingly perfect androids building it view Krug as their god. But Krug is only flesh-and-blood, and when his androids discover the truth, their anger knows no bounds... and it threatens much more than the tower.

"Some of them are looking for God, and some of them are looking for power, and some of them are just looking."
Simeon Krug, a brilliant inventor, has changed the world by creating synthetic humans in vats. They are so similar to humans that, to avoid confusion, Krug made their skin a reddish color and gave them no body hair. To these androids, Krug is God, but he doesn’t realize it. He thinks of them as mere machines and he’s set them the task of building a giant glass tower which will reach into the heavens to communicate with the aliens who have been sending messages to Earth. Krug’s son, poised to take over the company when his father dies, doesn’t share Krug’s obsession with talking to aliens, and he is particularly disturbed when he discovers the android religion. What will happen when the androids find out that Krug is not their salvation?
There aren’t any likeable characters here, and it’s hard for me to relate to androids, but Tower of Glass made me think (most of Robert Silverberg’s stories make me think). In Tower of Glass, Silverberg uses androids to explore a common science fiction theme: What makes us human? I’ve read dozens of stories which ask this question, but Tower of Glass will stick with me. Originally published in 1970, Tower of Glass has worn very well, probably because it deals with timeless human problems.
Krug’s androids, who call themselves “vat-born” to distinguish themselves from the “womb-born,” are constructed with human DNA which has been altered to give them a slightly alien look and to make them hard-working faithful servants. What Krug didn’t realize, perhaps, was that this human DNA would make them ambitious and would give them a desire to worship their creator. Under the leadership of Thor Watchman, the android who works as Krug’s right-hand man in the tower project, they develop an entire religion around Krug. In their time off from building Krug’s tower, they get involved in politics, build temples, write holy scriptures, hold worship services, conduct sacraments, chant and pray. Their chants and prayers consist of recitations of genetic code and their scriptures, modeled after the Christian Bible, speak of Krug’s love for them and his plan to save them by transforming them, with genetic code, into full human beings after they die. It’s understandable, then, that they’d be a little upset when they find out that their religion is false and that they’re not going to be saved after all.
As usual with a novel by Robert Silverberg, you have to suffer through some unpleasant sex scenes (I find many of Silverberg’s sex scenes to be disturbing), but there are fewer far-out tangents in Tower of Glass than in some of his other stories and at least here there is some purpose to them here. The pace moves quickly and Silverberg packs in a lot of ideas as he shows us a newly developing android society that is dealing with the same kinds of issues that humans have always dealt with — racism, caste systems, slavery, outcasts, ghettos, disease, drug abuse, political agitators, religious zealots, and the rise of an oppressed population. All the while Silverberg ratchets up the tension as the tower gets taller and Krug becomes more obsessed and noticeably less godlike.
I listened to Stefan Rudnicki narrate Audible Frontiers’ version of Tower of Glass. Rudnicki always gives a great reading — he has a nice voice, he never overacts, and he always seems to “get” what he reads. Tower of Glass was nominated for the Nebula, Hugo, and Locus awards.
I have just finished listening to "The Tower of Glass". and I strongly recommend it everyone, whether a science fiction fan or not. Some time ago I lost myself in the three
original Majipoor works. I found that I was discovering a number of nuances and
insights, particularly about the alien characters, from the readings, even
though I had read the print editions several times (ten-eleven in the case of
LVC!). Some of RS's books (although not all, unfortunately), are "read" by
writer/actor/director Stefan Rudnicki, who has a magnificent, booming, rasping,
gravelly voice that is perfectly suited to RS's prose. Just imagine what he
could do with "Lord of Darkness," although some judicious editing might be
Rudnicki's performances are not simple readings of the narrative, nor are they a
dramatic interpretation, but something entirely different. I believe that he
has invented a new vocal art form. I have heard things in "Tower of Glass" that
I had missed in previous readings, and which interested, fascinated and
terrified me. For instance, what would happen if God turned his back on
Humanity, and Humanity turned on God, as this is a story about androids and
their creator. For God, read Krug the entrepreneurial billionaire who invented,
manufactured and marketed androids, and androids as the end result of Human
This tale moved at a great pace, the story propelled by a tight group of characters and a compelling narrative about sentience, obsession, and humanity. Well read and thoroughly enjoyable.
My taste differs from kid books to gory horror books.
This is not one of Silverberg's best and it is not one of his worst. If you are already a Silverberg fan, I believe you will be happy with Tower of Glass.
I started reading Sci-Fi in the eighties and at that time Sci-Fi meant Asimov, Silverberg. Clarke and Pohl and then there were these upstarts, Bear and Haldeman. Reading any Silverberg story is like going home. He also wrote constantly, even under several pseudonyms. What all his books have in common are deep thoughts.You can not read a Silverberg Novel without being challenged Morally. You are forced to question. A Time Of Changes is probably one of his deepest novels.
Some five star Silverberg Novels are Downward To Earth, The World Inside, At Winter's End and House of Bones. He also edited Legends and Far Horizons which have to be the highest quality of short work from different authors, that you will ever find.
I am very excited to see Audible expand there library to include RS's older work and I hope to get to all of them.
Rudnicki is in a class all by himself.

I'm actually not a huge fan of Robert Silverberg. A lot of his other works ARE good, but they don't compare with Tower of Glass.
This novel, with great help from the narrator, was a great experience to listen to.
It brought the tired old, "the soul of the robot", science fiction cliché to a whole new level. I really, really, enjoyed this book. One of the main characters, Alpha Thor Watchman, is probably my new favorite fictional android.
Add it to your collection if you're ANY sort of respectable sci-fi fan.
