Let's get this out of the way first: YES I READ A LONG HARRY POTTER FANFIC. 
 Second: AND I LIKED IT AND PLAN TO READ THE NEXT ONE TOO. 
 This doesn't have the same exact flair as Rowling's Hogwarts. And that's fine. Lippert is more concerned with how things in the wizarding world work (his explanation of apparition was helpful) and I liked his thoughts on what Hogwarts would be like for the son of Harry Potter. I like that DADA is still being taught by a rotating cast of characters on one-year terms. I like that the social boundaries among houses seem to have loosened. I like that, for these kids, there's a knowledge that something major happened a long time ago, but it was before their time and so it's not really a thing for them. 
 I would have liked to have seen more of the established classes. (Who teaches Potions now?) And I really, really would have liked to have seen a couple more females in here among the principles. There are a couple of secondary (at best) characters; they're really more like tertiary for how relevant they are. 
 But as I said, I'm probably going to continue and read the next one anyway, so there is that.
