If you are familiar with time travel and the various philosophies and paradoxes involved, this book serves up just about every one. And in a mostly entertaining way.
The author has a way with women. First impression, the woman of this novel (and there is only one female character) seems a cringe-worthy product of a scientist’s fantasy. But like many of Asimov’s most memorable women-characters, there’s something more than meets the eye.
There are lots of cigarettes and a good quantity of sexism in this 1955 novel, but the plot structure and multiple twists give the reader a great ride. Recommended as a stand-alone novel independent of most of Asimov’s other series.
