YA book about 3 siblings find themselves in an alternate world only to come back 6 years later and not a moment has passed sister never the same after goes missing after going to a girls school.

[Hunter]

They try to find her through the perspectives of the sister and it jumps back through many timelines. Plural because the sister who is missing had a POV until her disappearance, and there’s flashbacks to the world they went to. I read this book like 2 or 3 years ago. I have completely forgotten the name and author. I want to buy and reread it but I can’t figure it out. I even looked at my library checkout record and still haven’t been able to find it.
