Os pecados da tribo (1976)

Hiya,
i just finished reading an interesting novel called "Sins of the Tribe" (originally Os pecados da tribo (1976)) by an extraordinar brazilian author of 20TH century. It deeply recommended me of the George Orwell´s novel 1984, because of the kind of totalitar system the main person lives in. Yes this is a joke: also i´m growing up on the background of a post-communist country, and i can feel myself in the skin of a person resident in this type of society. The problem is being observed all the time, and if not directly followed, felt as followed and observed in every tiny intimate moment of the life, or at least, behaving as observed without knowing it.
José J. Veiga, the author, maybe had known something close to conspiration theories, or had been scared of the mankind future. And had been interested in avionics as me!
