Terrarium

the long version

"In the 21st century, humanity has abandoned the Earth for the Enclosure: a network of cities, built from the salvage of the old world, sealed against all of nature. Within the Enclosure the human race lives protected, all its material needs provided for. Citizens hide beneath masks and layers of ritual and numb themselves with drugs. Within the Enclosure are a few people who want out. In Oregon City, a small group plans to escape to the wild Earth beyond the walls. United by something much more than just an idea, they meet in secret. But they are not unobserved. And what they find outside is not what they expect."--Jacket.
