Haldeman delivers another great sci-fi story. He handles the nuts and bolts of a trip to Mars and what life there would be like with his usual readable style that gives you some real science without a lot of technobabble. Best part of this story is the main character, Carmen. Telling a sci fi story from a slightly angry and rebellious teen-age character is a nice change of pace from the type of astronaut heroes we usually get in these stories.
