Magic schools or science fiction academies almost always make for good reading. JK Rowling made a billion dollars out of writing novels that almost never left the grounds of Hogwarts. Probably because the next step is almost always the hardest. I would argue that only Ursula LeGuin’s Earthsea novels every featured stories taking place after the magic university was finished that match up to (and even surpass) that time in college. Maybe it’s like real life. Nothing really beats those school days.
Credit to Kuang for trying and for writing a non-western themed fantasy. But she didn’t stick the landing. She struggled mightily and came close in this final book, taking the logical conclusion, while still giving her protagonist redemption… but it didn’t quite work.
