For q diary entry based book I actually didn‘t get emotionally involved with the MC at all. I didn‘t care about her and certainly was frustrated with her constant whining by chapter 3.
By page 100 I was 50% through the novel and 100% done with reading it.
Looked up the ending and started skimming. It was a terrible experience and the MCs Frances Burney obsession seems to have factual holes in it from my brief research.
