Book about parallel universes where only children could travel through

I read, maybe in the late 90s, a science fiction book about parallel universes where at first it wasn't quite clear what was going on -- children used some kind of slang for them that the adults didn't understand. Some disaster had happened, I think, so only the children could travel through the multiple worlds. There was a plotline about the protagonist's brother (I think?) -- his wife had died in that world, so in the end he went from world to world trying to find one where she was alive. I believe the protagonist was female and also the author. There might have been something about a house or doors or rooms moving around, or I might be confusing it with another book. Any ideas?
