THE BLUE WORLD, a beautiful world, a world of water, with floating islands made by the thick, spreading tops of gigantic ocean growths, big enough to support neat houses and sea 'gardens' alive with fish of all kinds, rich with edible water plants, and even communication towers so that the People of the Floats were not cut off from one another but could send messages and enjoy festivals and meetings together.

Except for one thing. The massive abundance of the ocean spawned far more than food and sustenance for the puny humans living on its surface. The Floats were in constant danger from the ravaging attacks of great sea creatures against which there was no defense — except mealy-mouthed propitiation.

THE BLUE WORLD needed a rebel, one who would give his life if necessary.
