Accidental creatures

A bio-technology corporation has created a new species, intelligent, four-armed, humanoid "tetras" who can live in the vats in which "the company" grows biopolymers. Both the tetras and the human vat-divers they were created to replace are at the mercy of vicious corporate politics. But soon the victims become the aggressors, and something amazing, a transcendent change, occurs not only in their lives, but throughout the world.
