Hello everyone! I've been for the life of me trying to piece together anything about this book, but there's absolutely nothing. I read it back in early 2018 as an assignment in high school (not an english speaking country, but the book was in english). As stated in the title, there are multiple references and parallels drawn to the moon throughout the novel, story and plot other than that I don't remember in the slightest. The only thing I do remember is the last page where the protagonist stands at a shore and overlooks the ocean/and or moon. My memory has betrayed me so the description is a little vague. Thanks <3

Is it fantasy? Moonflash, by Patricia McKillip might be it.

"The girl who drank the moon" might be it

Thanks for helping me out, you guys! I managed to find it at long last. It's Moon Palace written by Paul Auster.
