TITLE: The Dark Side of the Sun
AUTHOR: Terry Pratchett
"Dom Salabos had a lot of advantages.
As heir to a huge fortune he had an excellent robot servant (with Man-Friday subcircuitry), a planet (the First Syrian Bank) as a godfather, a security chief who even ran checks on himself, and on Dom's home world even death was not always fatal.
Why then, in an age when prediction was a science, was his future in doubt?"
This is a flawed early science-fiction work by Terry Pratchet, but it is still entertaining with rich world building and interesting characters.
