They were in the mountains. That was good. Lotte liked it when they chose mountains. A stocky man was sliding down a slope, feet out before him, legs stiff - too conscious of the camera, though. Lotte couldn't tell if he had meant to slide, but he did not look happy. She turned her attention to the others.This is an anthology of stories and writers which supposedly straddle the boundary between mainstream fiction and sf. I confess that I didn't really see the point of the question ("What if sf didn't exist as a genre, but was being written anyway?") but I did enjoy most of the stories. One or two I already knew ("The Ones Who Walk Away From Omelas", "Salvador") but the one I particularly enjoyed, contra my own expectations (also contra other reviewers who I've read) was "Ziggurat", an interesting and convoluted short by Gene Wolfe, who I've tended to bounce off in the past.
This was the most popular remaining book on my unread shelf which I had acquired in 2009. Next are two more collections, Vols 3 and 4 of the Collected Stories of Roger Zelazny.
