SOLVED. YA Novel, 2018: Collection of 5 or 6 Possibile Outcomes for the MC when she goes to a party(?) on an island. Variety of genres, only remember horror and mystery. [s]

The plot was that a girl had been summoned to an island for a gathering of some sort; I think it was a party being hosted by a distant relative she was unfamiliar with. However, the uniqueness of the book was that there were parts where the timeline deviated from another and we'd get to see possible outcomes of her time there. There were 5 or 6 possibilities, but I only remember a mystery themed one where she was trying to figure out who stole something (might have been a painting) and it ended with it being solved (I think she also kissed a girl in that story but not in any others), and a horror themed one taking place in the library. There was specifically a Winnie the Pooh book mentioned, When the MC got to the scene where Pooh was stuck in Rabbit's hole, instead of getting pulled out he became part of the walls. I believe the characters met a similar fate but I'm not certain.

I know I read this story in 2018 and in the spring, and it's possible it was published before then but probably not by more than one or two years. The specific version was a hardcover; it was silver and iridescent (I think that's the right word; it looked rainbow when you tilted it). No images on the cover except for possibly a fractured design which is why it looked iridescent.
