From the introduction: Imagine yourself - living on Turoc, fifth planet of the star Bellatrix of the constellation of Orion. Gravity on Turoc is so light that even with your egg-shaped body and short chubby legs, you can run and jump and glide with the grace and speed of a cheetah. Life on Turoc is always fun, and since your people are too wise to war among themselves, and everyone's needs are attended to, it is only natural that they have looked outward to the stars. It is the wisdom of Turoc not to disturb primitive people on other planets, but to observe and understand them. You have been chosen to visit one of the most fascinating planets in the galaxy. You are an Earth Inspector!
