The book is written by a castle enthusiast who went on a castle trip in Germany. I'm not German, I'm Dutch, but still for me it's very, very strange to read the word "Schloss" when plural castles is talked about. The plural form of English castle is castles. De plural form of a Dutch slot is slotten and of Dutch kasteel is kastelen. The plural form of a German Schloss is SchlosSER. For me it is completely silly to read "The castle are .." in English, but that's what's written all the time in this book "The Schloss are ...". That's annoying, and silly, and makes me not being able to focus on the content of the book. I was really disappointed by this silly booklet.
