Four-Day Planet
by H. Beam Piper
A four-day planet... Where the lethal heat of a millennial day drags people underground, and where the glorious hourly sunset follows a thousand-hour night, it is so cold that only an extreme perimeter suit can save the lives of anyone caught outside. Fenris is not the hell of a planet, but it is not traded by anyone. With 2,000 hours of day and 8,000 hours of year, it replaces scorching heat with deadly cold. Such a planet tends to give rise to a special type of person: tough enough to survive and smart enough to do as well as possible. When such a person discovers that he has been deceived by the wealth for which he risked his life, such a planet is ripe for revolution. This pre-science story will delight fans of politically oriented fiction.
