Just thinking of controlling families is considered a faux pas. In this world it is a blessing to have children: most people are married at 12 and parents at 14. The Urbmons are a world of total sexual license where men are expected to engage in "night walking" it is considered very rude to refuse an invitation for sex.


Farmers trade their produce for technology and the two societies rarely have direct contact even their languages are mutually unintelligible. The farmers live a very different lifestyle, with strict birth control.

The theoretical limit of the population supported by this arrangement is estimated to be 200 billion. The Urbmon population is supported by the conversion of all of the Earth's habitable land area not taken up by Urbmons to agriculture. Each building can hold approximately 800,000 people, with excess population totalling three billion a year transferred to new Urbmons, which are continually under construction. An Urbmon is divided into 25 self-contained "cities" of 40 floors each, in ascending order of status, with administrators occupying the highest level. Life is now totally fulfilled and sustained within Urban Monads (Urbmons), mammoth thousand-floor skyscrapers arranged in "constellations", where the shadow of one building does not fall upon another. War, starvation, crime and birth control have been eliminated. Most of the action occurs in a massive three-kilometer-high city tower called Urban Monad 116. Population growth has skyrocketed due to a quasi-religious belief in human reproduction as the highest possible good. The novel is set on Earth in the year 2381, when the population of the planet has reached 75 billion people. On March 2, 2010, Orb Books published this title as a trade paperback edition.
