I have read a lot of science fiction, short stories as well as full-length novels. There are about a dozen stories in this volume, which amazingly was released as long ago as 1954.
The stories are varied, entertaining and enjoyable. It's a bit like a music album where every track is great. I particularly like the story "If I forget thee, oh Earth" which must rank as the most inexpressably sad story I have ever read, for science fiction does not always tell of triumph and glory for humankind. This volume also contains the short story "The Sentinel", written for a Christmas competition in 1948, which was the embryonic storyline for the classic 2001:A Space Odyssey. The other stories are just as good. There is not one duff story in this book.
These stories were written when Clarke was at the height of his sf powers, with the grandeur which is his hallmark. I cannot give this less than top marks.
