This is a picture book covering all aspects of the Northern Campaign including the 1939 Russo-Finnish War, the 1940 invasion of Norway, the campaigns in Finland and Karelia from 1941-1944, and all aspects of the naval war in the Barents and Arctic over the same period. As a history of the events and campaigns, this is little more than a brief overview. The topics are so broad and the text so short that only the merest overview is given. All of the information can be found elsewhere, there is virtually nothing new. If you want to know anything about any of the campaigns nominally covered in this work, I strongly recommend that you find other books that are better written and more narrowly focused (such as Trotter's book on the 1939 Winter War or Ziemke's book if you are interested in the Karelia). There are lots of great (and rare) photos in this book, but little more. One thing that really annoyed me about this book was that the authors openly present a strong pro-Soviet bias. This is unacceptable in a scholarly historical publication by two professional historians (both have Ph.D.s). This should have been written with more balance, I can only conclude that this is not a serious work. My rating of three stars is, I believe, generous and I would not disagree with anyone who gave it two. This is a picture book of the Arctic war, and if you are looking for more than this, you will disappointed by this volume. Not recommended for a serious student of the era.
