Coraline is a children's book good enough to be organically read by adults. As it's fairly similar to the movie, I'll cover some not-so-obvious interpretations I had:
Throughout the read I couldn't help but feel like Coraline's other mother was a perfect embodiment of a BPD parent. Aside from the obvious BPD characteristics exhibited by the other mother, I felt the following quote summed everything up beautifully: "It was true: the other mother loved her. But she loved Coraline as a miser loves money, or a dragon love its gold. Int the other mother's button eyes, Coraline knew that she was a possession, nothing more. A tolerated pet, whose behavior was no longer amusing."
After reading the book, I found a great blog analysis that touched on the many thoughts I had throughout the read: pensievely.wordpress.com/2020/12/17/seduced-by-borderline-an-analysis-of-coraline/
BPD-aside, very fun book. Made me laugh a few times, a bit creepy, and was nice to finally read the book. I adore the movie.
