I really liked this story - it was engaging, had great character development, and mild mystery that slowly unwraps itself (in a slightly anticlimactic way). The author did the misunderstanding and unraveling of the misunderstandings very well. There was humor, sweetness, and growth.
However, I think the ending was disappointing. I love a nice face slapping, but mean, overzealous revenge against someone who already had dementia and is nearing the end of their life is just cruel. I think it's worse because we don't personally witness the injustice the revenge is for, but are instead just told about it. This made me skim the ending with one eye closed.
Also, I thought the use of wealth in the beginning of the story was funny and added to the story, but by the end, it was just a bit overblown, overemphasized, and embarrassing. I loved how the author showed wealth isn't a reason to discriminate in the beginning, but that moral felt lost by the end.
Similarly, I loved the focus on family, but the magical pathway for curing trauma felt... Well... A bit too magical. Therapists don't always have a cure, because some things don't really have cures. Many times, people just learn ways of managing and living with their issues. But if someone was to get cured, I guess it would be a child, with dedicated help from his family and professionals, over long period of time.
