2381. The planet is overpopulated. The vast majority of people live in urban monads, gigantic towers thousand floors where eight hundred thousand people crowded together. Each turn is a closed world with its rules, its hierarchy, and two single pricipes. The first is that the more we live, the more it is estimated. The second is the absolute freedom ... under pain of death. Written there over thirty years, this novel has not aged. It describes a world without complacency that wants civilized, but that is nothing but a prison world in its own way. Absolute freedom, erected here in totalitarian rule and reign over this little world called the Monad 116. And governs mercilessly. Will reflect, without doubt ;-)
