So, after having read the entire series of Harvey Black's Cold War books, I have just one point of critique towards the last book. In my opinion, it continued the very detailed story and mixture of grand-level storytelling and still keeping tabs with some individuals of both sides.
While the narrative continued on its own pace, the ending came rather abrupt and sudden. Also, what happened on the political level in the Kremlin is completely out of touch with aforementioned storytelling. The focus is of course on the action on the front lines, but in my opinion the political leaders of the Soviet Union do not need any introduction if their future actions are hard to understand. While the political ending in the Kremlin is not illogical per se, missing details of how we came to this point actually strengthens the feeling of 'sudden death ending'.
Still, I do like Cold War era books and this series did not disappoint me, quite the contrary.
