I struggled with this one. I really wanted to like it, I went to Catholic school and I knew some pretty cool nuns. There was a lot of potential in the premise. I thought this would be a fun time, despite being a murder mystery. It wasn't fun, it wasn't funny, and it didn't have anything new or interesting to say. It was just a series of awful people either doing awful things or having awful things done to them while the author describes how hot and humid it is every other sentence. (Do check the content warnings, there is a lot of dark stuff here.) The book is written in a stream of conscious sort of way, so I would be in a scene and then three paragraphs later the narrator was still musing, reminiscing about the past in a vague way, and talking about how hot it is, and I would have forgotten what was even happening. This was made worse by listening on audiobook and not being able to just flip back or skip over, but I do think Mara Wilson did a good job narrating the material she was given. Sister Holiday makes incredibly bad choices, is selfish and hard to root for, and doesn't really figure anything out that isn't completely obvious. The word "sleuthing" is heavily overused by her, especially considering that she doesn't actually do any. I would say the diversity is good, but because the diverse people are flat or terrible, I'm not sure the representation does anyone a service.
