This was a good ending to a good series. Could have continued, if not for the cancellation, but was also self-contained enough that the cut-off doesn't hurt the story.
Alterisse is an amazing character! Her part of the story was great, and I kinda wish we could have gotten an Alterisse novel besides a Herscherik novel.
One of the rare LNs that deal with slavery (mostly) right - both in having the modern person repeatedly mention how disgusting and creepy the whole institution is for them, and for having sympathetic "local" characters fighting for the recognition of slaves as actual people against the status quo.
