This tale is much more about what it means to belong than it is about the seemingly supernatural powers of the elite Grisha class. There's a lot going on here, much of it very involving. I enjoyed suspending my disbelief and entering into Bardugo's world. This is going to be a trilogy, I understand (and these days, aren't they all going to be trilogies?) but the first book wrapped up cleanly enough to satisfy me while I wait for the second. Solid writing, familiar fantasy tropes, and a suitably scary villain make for a book well worth picking up.
