The planet of Zarathustra sleeps quietly, the outright possession of the Chartered Zarathustra Company. However, something is about to wake it up. When Jack Holloway, a lone prospector out in the bush discovers a small humanoid race that might just be sapient, the company trembles. The company's claim to the planet is based on its classification as a Class III uninhabited planet, and the company is too big to be threatened with impunity.
But, the first of the little humanoids (Fuzzies) discovered knows nothing about charters and the law. Little Fuzzy joins Pappy Jack, and discovers a whole new world, a world full of fun and adventure. These are the adventures of Little Fuzzy, and his turning upside-down of a whole world!
This book was originally published in 1962, but is every bit as good today as it was back then. The story starts out a bit slow, but it picks up speed, and by the end you find that you can't put it down! H. Beam Piper was an author whose suicide tragically cut short what would have been a full and brilliant career. If you like good science fiction, set in a realistic and believable milieu, then I highly recommend this book to you.
