Can anyone recommend any fantasy containing worlds between worlds? I fell in love with this idea as a child when I encountered the forest between worlds in Magician's Nephew where each pond led to another world. And I liked Raymond Feist’s pub between worlds. But I can’t think of any others. I've asked this question before (not here) and received good recommendations of portal fantasy, which I love, but no one could answer my question directly. This type of story may not really exist. But I'll ask anyway.
