3.25? 3.5? 
 Hmmm. I liked some of the worldbuilding here, and the characterization is on point as always, but I also had enough of a misspent youth in Harry Potter fandom that a lot of it just felt weird, like if you laid out a spreadsheet of all the elements from Harry Potter and changed every other one so it was *just* different enough. Once the plot hit full speed I stopped caring as much, though, so there's that. 
 Assorted notes: 
 -Penny, you are a delight. 
 -I did like that there were certain elements of the setting that were like Harry Potter given a half-twist more realism, e.g. old blood families that are super classist but not straight-up Wizard Nazis and much greater integration with the Muggle Normal world. 
 -There were at least two lovely turns of phrase that made wish I was reading an ebook so I could highlight them.
