The time is the end of the 28th century. A world government is
attempting to deal with the problems created by a population
approaching one TRILION souls. Living space is at a premium; every
possible square foot of arable land is in use; and there still is not
enough food.
The only hope for ultimate survival lies in the long-awaited discovery
of an interstellar drive. And just as every resource is strained to the
breaking point, a new race, the Tritons, emerges from the oceans. They
mingle with the humans and they demand their rights as Earthmen!
The theme of dedicated humans vs impossible odds runs all the way
through this long novel. It's a good one, sadly lost to print.
