From back cover:
Humankind populates the entire solar system from icy Pluto to boiling Mercury. Great domed cities, humming factories, hordes of workers, all feed the power of the dictsfatorship that controls all life. Only a small group among the cowed populace dares rebel in a struggle that pits democracy against tyranny.
But there is a third force at work as well. A mysterious band of assassins whose final solution to the problem of humanity's fate is as terrifying as it is irresistible.
