Although these stories are probably 50 years old, they are mostly timeless. Okay, one or two have a slightly dated feel to the female characters, and there are a couple where the technology caught him out, but story after story was brilliant - really exploring the implications of different types of life and world for very ordinary human beings. I particularly liked the way he thought through the commercial implications of interstellar flight.
With the exception of the last two pieces (including the title story), which seem to have been strongly influenced by the SF 'new wave' urge to write something that doesn't make a lot of sense, these are some of the best SF stories I have read in a long time. They work so well on the iPad too. Highly recommended if you like this kind of thing.
