So many complicated feelings about this book. I love the idea, the evocation of the world was beautiful, especially in the blending of halacha, magic, and general antiquity. 
And it took Hisdadukh at least 2/3s of the book to come into her own as a character rather than as a pair of binoculars into rabbinic life and it was mostly her relationship with Rava (aka Rav Darcy) who made that happen. 
Some of that is the difficulty of writing children as characters contiguous with their adult selves. And some of that is in the way that the world overwhelms the characters. 
I’m so glad this book exists and also I am not entirely sure how I feel about it.
