This is an interesting collection of Clarke's short stories. Being written by one of the best science fiction authors of our age, the least someone can expect is to have great fun reading them.
Some of the stories, though, are really short, therefore they don't have much development, being just interesting concepts and mind teasers.
The longer ones are mostly the struggle of one central character against some hazard or life threat, based on scientifical facts used to develop the whole plot.
Since Clarke wrote those stories between the sixties and early seventies, it's also interesting to see what expections people related to science had thiry or forty years ago, and notice that science developments had taken a totaly different turn, now mostly applied to our day-to-day life.
In all, this book is less complex than other Clarke books, like "Songs from distant Earth", or "Rendezvous with Rama", and easier to read, but not more enjoyable. Read it to complete your Clarke-knowledge.
