The Reading Prismatic Arch discussion

I thought I'd start a mid-book thread so we can get some discussion going, even if we're not through with the book. So, thoughts on the first three parts of the book?

I love the set-up, and how Death either hints or just straight up tells you what is going to happen later.

The spoilers definitely make the story unique! I like how you get to know the characters pretty well from the beginning.
