Kay Kenyon's The Entire and the Rose: Part of a Modern Classic?
Imagine "a five-armed radial universe that exists in a dimension without stars and planets and is parallel to our own universe. Stretched over the Entire is a lid of plasma, called the bright, under which live many galactic species, copied from our own universe."
Can't imagine that? Okay, it's tough for me, too, and I was reading Isaac Asimov when I was three while benchpressing a copy of Stranger in a Strange Land.
Okay, how about this instead: Kay Kenyon's Bright of the Sky and just-released A World Too Near feature a brilliant SF setting that rivals Larry Niven's Ringworld and Philip Jose Farmer's Riverworld series for sheer invention, adventure, complexity, and a sense of wonder.
The storyline involves the Quinn family--it is Titus Quinn who breaches the divide between our universe and the Entire. It's Titus who must go back to try to save his wife and battle his daughter, who found her way to the Entire in book one. In addition to the evolving family dynamic, there are wars going on between rival factions of alien species. Not to mention a continuing exploration of the strangeness that is the Entire.

Coming to a divide in the hall she took the left branch, remembering her partial and wholly inadequate map. This hall too was deserted, and she rushed on. She prayed not to be discovered, although she had her alibi, thin as it might be.
