The elite government officials of the Polite Harmony of Worlds use specially designed clones called probes to collect and analyze data for them. Probes like August have enhanced inteligence and senses, but they are slaves to their electors, and they are genetically programed to die young of a condition called 'flare' which causes their metabolism to increase until they cannot take in enough calories to sustain them and they starve to death. To add to his misery, August is a clone of an infamous probe, Allexander, who betrayed his masters to reveal the truth about a plot that is still in play.
