Review: This book is a fascinating exploration of the last days of the Soviet Union, providing a background of the broad mix of events and people involved both before, during and after the Gorbachev era. It maps the mindset and events during this dramatic change. It is told with a direct, personal style that I found gripping, and that gives a very good sense of the societal changes and impacts. I highly recommend it.

Output:
False
