We all take different impressions of the books we read. You are allowed to dislike it!

Some of the weird advertising refers to the book as hilarious. ????

No way, it's about a woman who is probably not neurotypical, dealing with an awful past trauma.

Her behavior is not so good, e.g., stalking the musician. I can still sympathize with her. I would say that the past trauma does not explain all, I think she was autistic.

At the end, she is healing, so that explains the title.
