Query: Chilling look at results of socialist revolution

Koestler motivates a terrific theme of the dehumanization of man through assimilation by the state. The protagonist, Rubashov, takes us through memories that lead us to realize that we could all be delinquents of a socialist state. His feelings begin with understanding for the revolution and support of the positive changes the revolution brought along. The feelings become more of a Randian nature as Rubashov realizes the great error of the people.The thematic quality of the book is near that of any of Ayn Rand's novels while the prose surpasses even Rand's greatest. This is a must read for any with love for twentieth century literature; or anyone who has felt the link to self exhibited in the Randian philosophy.
