This is an interesting collection! The editors said their goal was to assemble fiction from beyond the edge of conventional narrative, and they definitely succeeded. That does mean, as a consequence, that many of the stories are simply odd. Which oddity appeals to each reader will probably vary.
For me the standouts were:
Omens by Carol Eschwiller- Told by a lunatic, it was impossible to fully discern reality from fantasy, but the narration was compelling, the worldview alien yet understandable
Falling by Raylyn Moore- I rated this story only a 3/5, because it lacks a conventional narrative. It makes up for that in imagery and the peculiar logic on which its world operates.
Suzanne Delage by Gene Wolfe- I didn't like this story at all until I read more about it. It's long-winded, there's no real plot, and the main character is uninteresting. It's easy to simply not care about the central mystery, but once you start thinking about it, the story turns into a puzzle box.
The Oracle, the Ballad of Bowsprit Bear's Stead, and The Finger are also quite good, but I think they'll stick in my mind less.
