It’s not clear whether this book is fact or fiction, it presents as a diary recovered from a German prisoner-of-war, as a factual record of his progress through the German navy and the first World War. But there’s not a lot known about it so it could be fabrication. Regardless, it does a great job of showing how human both sides of a war can be, people just doing their jobs, falling in love, missing home and doing their duty. A good, quick, read.
