As action-adventure, the stories in this collection of short fiction are very good -- engaging, imaginative, and with interesting leading characters. The first three are set in a society in which security cameras are omnipresent; people are not always watching you, but your every move (and "every" is not hyperbole) can be reviewed if need be. The stories show how such a system can be used, but only one speaks of misuse, and that is local and transitory. All three of those stories have plots which deal with ways around the system (political power, invisible action, and going underground), and all three have themes of personal vs. societal justice. I did not find the plots wholly plausible, though they held together enough that I could enjoy the stories.
The other two stories stand alone. "Travellers" is a travelogue crossing 19th-century United States in a dirigible whose captain is apparently from the future. "Time Safari" is an adventure story about hunting dinosaurs, complicated on this trip by a churlish coward. Both are enjoyable reads, but not terribly deep.
