Rails must be freshly laid ahead of the city & carefully removed in its wake. Rivers & mountains present nearly insurmountable challenges to the ingenuity of the city's engineers.

The secret directorate that governs the city makes sure that its inhabitants know nothing of this.

Yet the city is in crisis. People are growing restive. The population is dwindling. The rulers know that, for all their efforts, slowly but surely the city is slipping ever farther behind the optimum. Helward Mann is a member of the city's elite.

    Clarke of Last and First Men. This masterpiece of science fiction by British philosopher and writer Olaf Stapledon (1886–1950) is an imaginative, ambitious history of humanity's future that spans billions of years.

It evolves through the ages: rising to pinnacles of civilization, teetering on the brink of extinction, surviving onslaughts from other planets and a decline in solar energy, and constantly developing new forms, new senses, and new intellectual abilities. From the present to five billion years into the future, this romance of humanity abounds in profound and imaginative thought.

    When famous adventurer Sir Richard Francis Burton dies, the last thing he expects to do is awaken naked on a foreign planet along the shores of a seemingly endless river. But that's where Burton and billions of other humans (plus a few nonhumans) find themselves as the epic Riverworld saga begins. It seems that all of Earthly humanity has been resurrected on the planet, each with an indestructible container that provides three meals a day, cigarettes, alcoholic beverages, a lighter, and the odd tube of lipstick. But why? And by whom? That's what Burton and a handful of fellow adventurers are determined to discover as they construct a boat and set out in search of the river's source, thought to be millions of miles away. Although there are many hardships during the journey--including an encounter with the infamous Hermann Goring--Burton's resolve to complete his quest is strengthened by a visit from the Mysterious Stranger, a being who claims to be a renegade within the very group that created the Riverworld. The stranger tells Burton that he must make it to the river's headwaters, along with a dozen others the Stranger has selected, to help stop an evil experiment at the end of which humanity will simply be allowed to die. --Craig E. Engler
