(.5 because initially enjoyed the strained relationship of the siblings but even that fell flat for me later)

1. This book was incredibly dull. Like my eyes were losing focus on the page dull.
2. TW: Sexual assault as a plot device is just ...
3. The first 2/3 book is figuring out a bunch of information that does not matter at all.
4. The ending made no sense to me because the motivation didn't seem to match any part of the characters up until that point.
5. You could basically cut the middle 30 chapters from the book and tell the same story.
