Note that I got this book (Book 1 of the series) because it was free, and do not plan on buying the sequels.
Nazi Germany was complicated, so learning about it is almost always a "big picture" experience. "Children To A Degree" is unique because it aims not only to fill the gaps, but to start from the opposite end of the spectrum. It focuses entirely on the average, day-to-day lives of children and families in Nazi Germany. It's not about Auschwitz, not about Hitler's cabinet, and not even particularly about Hitler's ideology and intentions. It's about the children and the families, the way these things permeated their lives. It's about the first concepts they learned about Hitler and Nazism, the way they interpreted these changes, the food rations, the way schools changed, the way the lives of women changed, and things as simple as learning the salutation "Heil Hitler"...
The book paints visual pictures with details that stimulate the imagination, making it easy to understand and picture yourself in such a world that otherwise seems so alien to our own. Even phrases like "Heil Hitler" and "Hitler Youth" said so casually by the characters in the book are part of the experience and you start to understand what it was all like, even if they still sound jolting and out-of-place to your ears. The book doesn't bother to demonize even those who somewhat blindly followed Nazi doctrine - because that's not the point. It also doesn't infantilize Germans, making them sound as if they were entirely free of autonomy and independent thought at the start of Hitler's rise to power, as if reading a headline made them instantly succumb because they were just empty-headed nothings waiting for something to tell them what to think - that's something I've seen in the past and though it's well-intentioned, it's wrong. This book doesn't do that and I really appreciate that.
"Children To A Degree" is honest and simple, even to a fault. Some details were easily skimmed - the pages on the physical construction of the train cars that carried children to their new schools, for example, lasted too long for my taste. That kind of thing lead to a bit of skimming... I skimmed through partial pages and full pages at a time.
The writing style is something that I really don't like. I can't really pinpoint the style but it reminds me of children's books. Many, many scenes have the same formula: Grandfather gives a long lesson in a metaphor-filled speech and the young child replies, "So, Grandfather, do you mean to say..." and gives a perfect, mature, concise summary of the grandfather's lesson. That's something that I see in children's cartoons and books, often. It's something that happens in this book about a dozen times.
As far as editing goes... was there any third-party editing? There are grammar issues and awkward syntax issues, even considering that we're going German to English. I laughed when I saw "mute issue" instead of "moot issue" but there was more than that. The children speak so unnaturally, and that is considering the difference in culture and time period. The dialogue is sometimes painful.
When it doesn't feel like a children's book, it feels like an insert from a history textbook. It's fully based on real facts and real situations but is rewritten in novel form, I suppose to help visualize it. It reads somewhat like a novel, but it's really not - it just feels like the information is poorly presented. That's the thing I couldn't really get past. I feel like parts of it could be shortened and put in a high school or college level textbook with some photos depicting what's being described.
So aside from my issues with the writing style, I did take away a lot from this - I saved quite a few historical facts and anecdotes. Some of those things explain the mindset of Germans in the era (how neighbours felt about each other; the fact that left-handed people could nearly never obtain employment if their handedness was known) to flat certainties (German laws on equal advertising or lack-thereof and equal mandatory business hours). I learned quite a bit about the things I wanted to learn about when I set off reading the book, so I'm not unhappy with the time spent reading it.
