I was browsing reviews after finishing this book and I truly think that anyone who was disappointed the lack of spookiness is missing the point. I love a good ghost story as much as the next person, but what was even more interesting to me was Mei's experience as the daughter of immigrants. Everything she goes through in this story is 100% authentic.
On the surface, Shadow Girl fits the template of your standard gothic ghost story: lower class young woman finds work as a governess (or in this case, academic tutor) for a wealthy family living in a remote location with a beautiful, yet troubled mother; a distant, mysterious father; a rakish, attractive half-brother the same age as our protagonist; and of course a precocious, imaginative young daughter haunted by a ghost who may or may not really exist. Even the creepy-housekeeper-strangely-devoted-to-the-family-and-rude-for-no-reason-to-the-protagonist makes an appearance. But the story is different from most gothic ghost stories because of the protagonist herself: she's the daughter of Chinese immigrants, and she's othered not only because of her social status but because of her ethnicity as well.
The instances of racism are subtle, but they ring true to any minority living in America. Mei endures a long cab ride where the driver blabbers on about Korea even though she isn't Korean. She attends a wild party full of wealthy teens her age and it's really obvious that she's the only Asian there, AND she's mistaken for another girl the whole night. She is self-conscious about the meal her mom cooks to share with her wealthy eventual-friend, Henry, even though it's her favorite food. She sacrifices her own dreams of going to a her dream school, a distant university, because she feels guilty about leaving her mother behind. And of course, again and again she's reminded that she doesn't belong in the Morisons' world - even though she has never once forgotten that fact. As a daughter of immigrants myself, these were all highly-relatable situations.
I just want to point out one scene that really stood out to me, where Mei is getting ready for the fancy surprise birthday party. She takes off her golden stud earrings, handed down to her from her mother, who got them from her mother, and replaces them with a pair of silver earrings regifted to her by her employer. In order for her to try to fit in with these people, she has to shed a part of her identity and put on something more fitting, but the golden earrings are an heirloom, while the silver earrings came from someone who gave them away without a second thought because they actually meant nothing to her. I thought this was a great job by the author of combining Mei's experience both as an ethnic minority and as someone who came from a poor background.
The paranormal aspects of the story were much more subtle, relegated mostly to strange bumps-in-the-night and gruesome nightmares. But again, I don't think that the spookiness was so much the point of the book as it was the way through which Mei is able to develop. Which, by the way, I really loved her character development through the story. She often does this thing where she thinks something but then says something else, except much more politely, and I feel this SO MUCH. What's even better is by the end of the book she starts actually saying these things out loud, and she no longer cares about appearing nice or friendly. GET IT, MEI!
There was also a bit of social commentary/scathing criticism of the 1%, which was much appreciated, but even though Mei aspires to work in finance one day, you completely understand why - as someone who grew up watching her mother sacrifice for everything they ever had, of course Mei wants a career that will help her make her mother's life easier!
Anyway, I really loved this book and I'm sad that people wrote it off because it wasn't strictly a horror story. It's much more a coming-of-age story, and I'm so, so grateful that someone wrote one that we can relate to.
