Well, I've now read "Manhattan in Reverse" and I can reccommend it. As Hamilton comments in his introduction, most of the stories are only called "short" because they're shorter than a novel and with Hamilton routinely using 1000 pages + to tell a story in the novel format it is no surprise that this entire collection consists of only seven or eight stories. The first few are set in completely new universes for Hamilton with the last couple, including the title story, solidly based in the same universe as his last half dozen novels. While I was obviously most comfortable with the two Paula Myo stories, the one that captured my imagination the most was "Watching Trees Grow", a murder mystery set over a period of a couple of hundred years from 1850 - 2050 in a universe not entirely unlike our own but populated by people with 400 year lifespans and, probably as a result, a slightly accelerated technological development history. I'd like to see Hamilton set more stories in this universe and perhaps even explain what the "Sport of Emperors" really is. One of the Paula Myo stories was a bit underwhelming as it relied on a plot twist that was used extensively in the Void novels so came as no surprise when it was revealed to be at work here. The character development of Paula was encouraging, I've always felt she was a bit too unecessarily one dimensional in the novels. The other one, involving the possibility of a non-diagnosed proto-sentinent species on an outlying planet had a well worked plot but the use of Paula as a main character seemed a little contrived. Perhaps it would have been better done as a stand alone story.
For Hamilton fans, and for fans of science fiction short stories, this volume will provide a short but enjoyable read.
