So far I liked this one the most, it felt like it took a page out of Tolkien's Hobbit. There was a grand-scale adventure with an end goal in mind and the adventure felt natural rather than “we have to do this because the plot demands it“. This would have been a solid 4-star hands down, except for the sexism that came out of left field at the moment.
“The school was bad because a woman was in charge, by the way“ isn't exactly a gotcha.
I'm not sure how to feel about Lewis basing the character on his Gardner and giving him all these negative traits. (not that a character shouldn't have flaws, but his treatment in the book is a bit unkind) 5d
