Girl singer gets rescued from exploitation from rich guy, so she can sing with the rich guy's possibly haunted automaton. Automaton turns out not to be an automaton. Rich guy and automaton fall in love with girl singer. Girl singer likes rich guy okay and maybe loves automaton. Automaton in danger. I could go on, and perhaps I should because this novel feels like a prequel to me and comes with the first chapter of the sequel.
I read Magic Under Glass partially because of my continuing quest to read more books by authors of color. The cover depicts a young woman who appears to be of color, but I don't think the author is. The protagonist does have elements of otherness in her description and faces discrimination, so it's not the worst imagining of a POC's experience by a non POC. There does seem to be an awkward pendulum swing, though, of authors of privilege trying to get in on the diverse books movement. I'm not saying they shouldn't, but what I'd really like to see is editors and publishers working harder to get out books by POC themselves.
