I almost stopped 25% in, made it halfway then realized I’m not engaged and don’t care what happens next. It has all these pieces I normally like (the appearance of mysterious magic loner mentor helped me get to the halfway mark), but I just don’t understand why the main character is sticking around for the upcoming fight to the death with her sister. I can guess at a justification, but so far the book has provided excellent reasons for her to get out of there and none for going through with it other than that it’s expected.
