Just like the other Hangman's Daughter books, this one is fun to read and fairly educational about the peoples, times, and places of 1600's Germany. As an American, public -schooled millennial, I don't have a firm grasp on the culture or happenings of anywhere foreign, (and, honestly, our own history is typically taught by disinterested coaches, and thus vague, disconnected, and irrelevant.)
I was relieved the author finally abandoned his "everyone should be aborted" campaign that was so prevalent in his early books, particularly books one and two. I suspect he had his own children, and now focuses more on the positive aspects of reproduction. Despite the insistent concept that, despite high mortality rates , nobody wanted children, his books have ALWAYS, had a very strong family theme and focus, which is refreshing and vital.
There is a somewhat politically correct focus motif, but It isn't spelled out till the end notes. The dichotomy of " we don't want to have children but we need more people, so we brought in other people that aren't meshing well" is a theme that is revisited throughout history, a current and prevalent issue, and perfectly applicable and pertinent to this story. In my mind, sometimes "different" is not only fine, but wonderful and replenishing; and sometimes it is harmful, diluting, and wishes you unwell. Each case is different.
His books are violent and raw, but not so graphic that they wouldn't be appropriate for high school on up. There is mild cursing, no f-bombs, and lots of tense, uncomfortable, and dangerous scenarios including, torture, rape, murder, etc...
