About spies infiltrating Nazi groups in America, obvious trigger warnings for racism against anyone not "Aryan". It humanizes the American Nazis to make a point about how they aren't monsters but people who choose evil, and how we must be aware of how those ideas spread. As one of the characters says, "nice isn't the same as good, they can be kind to you while spreading evil ideology", but it can be difficult to read the sympathy towards some of the characters or Veronica realizing how by being under cover and repeating the evil she can see how someone would believe it.
