"Like Pohl and Kornbluth's Space Merchants this is a novel of sophisticated government deception in the near future, an exploration of political corruption. Written in 1957 when Silverberg was 22, the novel is cynical and highly suspenseful. Silverberg, long recognized as a great science fiction writer, is a multiple award winner."@en . . . .
