Carmen Dula is nineteen years old when she moves to the Mars base with her family on a five-year assignment. She is an intelligent, level-headed (remote) college student who falls in love with the pilot. The journey and stay present challenges large and small, both regarding survival itself and getting along with the other residents. Then one day she wants to spend some time alone and unwisely takes a walk outside without a buddy. She falls into a hole and is rescued by a Martian.
Wait, what? I did not see that twist coming. I thought this was going to be about colonizing Mars. I suppose I should have read the blurb which blatantly alludes to it. As so often happens with Haldeman, the familial way in which his first-person protagonist speaks to the reader lulls us into a sense of false security about where the story is going to go. What starts out small and almost ordinary balloons out or proportion in unexpected directions as suddenly this everyman (or in this case everywoman) has to make decisions that affect the entire human race.
