Okay, so obviously this book was stunning. Like stay on the couch after Shabbat ends because I desperately need to finish it levels of stunning. 
Lemberg is very clearly and deliberately writing within the fantastic tradition of Le Guin—they write with Le Guin's passion for thinking about what it means for magic to be in community and how it's used and who can use it and how we bear the scars of our lives and still reach to do good anyway and Lemberg, like Le Guin, understands failure and its place in the story and the need to love the fallen as well as the victorious.
Which is all another way of saying that this fantasy novel is SO JEWISH. Not just the etrog and shofar and growing out of twelve, but things like possibly ineffable names and fixing/healing/repairing and families and forgiveness. And also stories about exiles and leaving home and where we locate our identity and the ways in which we are beholden to those who have come before us and their trauma and...I could go on, but just read the book.
Also, Erígra Lílun may have taken top spot in my list of autistic characters to whom I relate so hard that it almost hurts. "Perhaps I could be the one to do this, but I can't actually do this, not the way you are asking me to, not now, not like this." OOF. Good, but OOF.
Anyway, it was perfect and I can't believe it's done.
