I love short stories, and this book had quite a few that have stuck with me, which I say is a good gauge of an effective collection. Definitely an adult collection, and darkly reflective of the times. These stories do a nice job of extrapolating into the future without being ham-handed, and some paint pictures in a very movie-like way. As a matter of fact, one of my favorites in this collection I want to turn into a movie. Which I would do, if I had the time. And money. And talent. And knew what I was doing.
This collection has 14 short stories, including "The Calorie Man" by Paolo Bacigalupi, which was the inspiration for The Windup Girl. "Finished" by Robert Reed is wonderfully disturbing. "Little Faces" by Vonda N. McIntyre, the second story in the collection, does a fabulous job of making VERY alien biology seem completely believable. "Understanding Space and Time" by Alastair Reynolds is my favorite, and if you don't turn it into a movie, I will!
