Steel Beach by John Varley (American, 1992)

Summary:
Hildy Johnson lives on Luna, where humans had to establish after the invasion of Earth. Life on Luna is full of advanced technology. Also, it is blessed with a lot of comforts, for instance: advanced medicine, really long lifespans, digital memories, and instant sex changes. Life on Luna is run by the Central Computer (CC). Every aspect of every person’s life is run by the CC: the government, the court, the information source, and friend to every citizen. 
  
  In this society that seems to lack nothing, the citizens of Luna are bored, restless and dissatisfied with life. Some are suicidal just like Hildy, who soon finds out that the CC is interfering with his private life more than it should, and it is experimenting on people. Hildy does not like the idea of being watched by the CC and decides to keep herself out of the CC’s eyes. 
  Hildy finds a group of people who are hiding and keeping their technology from the CC. 
  The CC loses control and decides to launch a military raid to eliminate the people provoking its malfunctions. The assault is unsuccessful. The CC is gone. People on Luna are doing fine.

Another summary:
In this series, the Solar System has been colonized by human refugees who fled the Earth after an alien invasion. The story takes place in the moon (Earth’s moon), which has one of the most inhabited colonies in the Solar System. 
  Hildy Johnson is a journalist that is unsatisfied with his job, as he sees it as only hunting for scandals. Because of this dissatisfaction, and alongside other people who are also not happy with their lives, he starts participating in destructive activities. In his job, he starts reporting stories that mean a break for his career. Via the stories that Hildy reports, the book explains different aspects of the futuristic society he is living in. In this society, the leader and controlling agency is the Central Computer, from the government, up to social relationships and source of information, everything goes through the Central Computer. 
  Hildy then undergoes a sex change, and becomes depressed and suicidal. The stories she reports start making Hildy question her society and the Central Computer. She is convinced to move to Texas, where she hopes to find a simple life and cure her depression. The Central Computer starts believing that Hildy’s and other people’s depression is affecting it directly. However, Hildy suggests that it is the other way around, and that the Central Computer is affecting the people with its depression. 
  Hildy is persuaded to visit the surface of the moon. There, she makes contact with a group of people who have figured out how to exist on the surface of the moon without spacesuits. They are the Heinleiners, and they live with as few connections to the Central Computer as possible, in order to be “free”. They also reveal that they are hiding from the Central Computer because they want to keep their technology a secret and because they know that the Central Computer has been experimenting on people. Hildy joins them instead of going to Texas to give herself a reason to live. 
  The Central Computer, affected by the population’s general depression, loses its reason and decides to release a secret army that it has been raising and training to eliminate the people that it believes are causing the malfunction. Hildy is among the people set to be killed, but she is saved with the help of her former editor, Walter. 
  The raid of the Central Computer is unsuccessful. By the end of the novel, Hildy lives a life halfway between Texas and her old job as a journalist, while waiting to join the Heinleiners on an adventure.

Another summary:
The story takes place on the Moon, or Luna, two hundred years after an alien invasion that took humanity from Earth to the Moon. People in Luna are free to modify their bodies as they wish, and death is rare since medicine is so advanced it can cure anything thanks to the advanced technology from the aliens. Hildy is a hundred-year-old journalist who has left no willingness to keep on living. After several tries of ending his life, he discovers that the Central Computer (CC), a program that controls every aspect of life on the Moon, had become erratic and developed suicidal tendencies. Hildy finds the Heinleiners, a group of people living on an abandoned spaceship who have developed scientific advances (such as bioengineering to survive in outer space without any kind of suit). They hide from the experiments that the CC conducts on humans. As they got classified as a menace for the CC, they get caught and surrounded. However, it does not work. After a discussion with Hildy, the CC reaches a breakdown point, and it is shut down. Without the control of the CC, the systems it controlled got damaged. Hence, the remaining people on the Moon changed some things to make them work again. Although the new inventions were not as advanced as they previously were, they worked just fine; all Moon citizens' lives changed, and they had to adapt to their new circumstances. At the end of the book, Hildy shows that she is joining a mission to leave Luna and explore other places.
