A solid collection of Clarke's short story output during the 1960s. As a collection, it's not as solid as The Nine Billion Names of God, which was more of a "best of" collection; nonetheless, it's a lot of fun to read through, and nicely demonstrates Clarke's skill at sci-fi, whether it's epic in scope or even light and fun. There's a lot of Clarke's "stinger" stories here (stories with that closing last line that either twists everything or provides the whopper of a conclusion), and they're fun, but more impressive are some of his more luxurious, relaxed stories. The title story, for instance, details a remarkable race on solar winds, and Clarke's patience and grasp not only of pacing but also of the beauties of his world give the story a remarkable feel. The collection ends with "A Meeting with Medusa," a story that reminded me a lot of Lovecraft's "At the Mountains of Madness" - not as a horror tale, but more as an exploration of an utterly alien land, with loving detail that truly creates an image for the reader. If you can find The Nine Billion Names of God, it's a better collection, but you could do far worse than this for a demonstration of why Clarke is such an essential name in science fiction.
