This was Arthur C. Clarke's first published collection of short stories. It includes "The Sentinel", which was the starting point for the film "2001: A Space Odyssey".
Clarke always had a more delicate and poetic side, and this collection includes one of his finest stories along this vein, "Second Dawn," in which telepathically gifted aliens without hands deal with the moral dilemmas of science. Many of the stories address a Space Age that never was--Clarke was assuming that things would happen later than they did, but that more would follow quicker; this in itself gives the book charm as an add-on to its considerable conceptual wit. Few short story collections are SF classics, but this is a major exception. --Roz Kaveney, Amazon.co.uk --This text refers to an out of print or unavailable edition of this title.
