Plot

Bass' future Earth is a single species environment in which the sum of the biota serves as its food chain. Human science has created the four toed Nebish, a palid, short lived and highly programmable humanoid who has had the elements that do not facilitate an underground Hive existence (aggression, curiosity, etc.) bred out of it. The five toed humans (called buckeyes) wander the biofarms that keep the trillions of Earth's Nebish population fed. All animals other than man are extivct, so meat comes from other humans. The conflict between the Hives and the roving bands of five toed original Humans, who are reduced to savagery and hunted like vermin by Hive Security forms the backdrop of this novel.

Something Strange is happening, as the primitive buckeyes are showing signs of a purpose whose goal is unclear and probably dangerous to the balance of the Hive. There seems to be a Third Party stirring the pot, campaigning in a relentlessly successful battle with the computer Minds that keep this Brave new world in balance. Agendas beyond the ken of their protaganists begin to come into play, and an epic battle between the Four and the Five toed is looming.
