Title: Enjoyable Heinlein juvenile
Review: No one was a better SF storyteller than Heinlein. I especially like his engineering description of a spacesuit, and explanation of motion equations. Good hard science based fiction there. The far out intergalactic travel stuff is fun too. There is one thing about the novel that bothers me, though: Since it refers to a lunar base and a space station, it's obviously set in the future, but Heinlein makes almost no effort to make the reader believe Kip is actually in a future society. In fact, it's rather obvious that the book is set in the year it was published--1958 (there is no way a soda fountain drink costs only 35 cents in the "future").
Is the review positive or negative?
