The Yawning Heights, by Alexander Zinoviev. New York: Random House. $6.95.

Zinoviev integrates satirical analyses and prophetic warnings in this acclaimed work about the myths and realities of the 60-year history of the Soviet Union. Set in imaginary Ibansk (a vulgar pun and nickname for Russia, and in a way for the world), Zinoviev reproduces a nightmarish world where "social laws" have replaced ethical standards. The author, an eminent Soviet philosopher, lost his citizenship over this compelling, unorthodox book.
