The retrospective ones are always slightly harder for me because memory is not always a thing for me so it's very "who is this person".
Not that it really matters. I loved this one. The ways in which it was sad and difficult and about los(s|t) and successfully talks about the two at the same time and the difference between misplacing and having something taken away and choosing to give up and, ugh, beautiful.

Also, I had listened to Dr. Nicole Bedera talk about trigger warnings last week in a super interesting podcast and then thinking about what Seanan does with her content warning at the beginning to do more than warn, but to actually help and provide reassurance in a way that almost feels like part of the story.
