Following death of the Soviet premier, the head of the KGB gains control of Moscow in a partially successful coup but also triggers a full-scale, nuclear civil war
I read this book in summer of 1986 right after it was published. I was on an operation in the Bay of Adak, AK with a Rapid Deployment Task Force at the time as I was serving in the US Marines. The fun part then was that the Russians were still a Communist country and the Task Force actually chased Russian fishing trolley's out of the Bay before our beach landing operation.
The story kept me thrilled and I recall it was the fatest 192 pages I ever read. For a fictional account of "what was" it provided a great story backdrop to my real life experiences at the time.
