intercultural space in outer space vs CCCP

Go into this book and discover:
- The diversity of the peoples of the former empire CCCP: rural, polar urban mix to give a fragmented view of Russian culture;
- The power and excitement of the Soviet astronautics, supported by the courage and energy of its cosmonauts ready to give their lives for space quest.

The writing is rich, the wise and colorful words.

A flat completely personal: I tired quickly enough of these epistolary exchanges, and historical descriptions where finally some things happen.

If you like or want to discover a facet of the Soviet Union, then read this novel.
