Publisher's Summary:
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.

Critic Reviews:
"[A] multi-leveled work of high adventure, considerable tension and social consciousness." (Harlan Ellison)

Deep Thoughts
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.

Androids are people, too.
Any additional comments?
"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 doesnt realize it. He thinks of them as mere machines and hes 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. Krugs son, poised to take over the company when his father dies, doesnt share Krugs 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 arent any likeable characters here, and its hard for me to relate to androids, but Tower of Glass made me think (most of Robert Silverbergs stories make me think). In Tower of Glass, Silverberg uses androids to explore a common science fiction theme: What makes us human? Ive 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.
Krugs 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 didnt realize, perhaps, was that this human DNA would make them ambitious and would give them a desire to worship their creator.
