Please help me find a specific book

[readinginstars]

So, I saw this book on BookTok last year, that I've been looking for but can't find anymore. I don't remember the title or the writer sadly, but I remember the whole book was made of notes passed to each other by the two main characters.

If anyone remembers it, or has any guess which book could this be, please let me know.
Thank you if you can help ❤️

i think you're talking about “divine rivals” by rebecca ross, right? that book was crazy hyped on booktok last year! most of it revolves around them sending each other letters. i'm pretty sure that's the one you're thinking of, right? :)
