I was disappointed with the first volume so I delayed before reading the second. It was an error. This was a much more enjoyable to read and seems to have more content. Whereas I felt the Prussian volume skimped on all but the architecture and the organization because anything else was proper only to another series like the Campaigns, this volume tells you much more about the history, and the story of these castles is fascinating. You won't find much written about Baltic history and Turnbull is a great story teller. I only wish it was twice the length. Highly recommended.
