The Billion Dollar Boy — Charles Sheffield

Spoiled and hopelessly, bored, Shelby Crawford Jerome Prescott Cheever V is one of the richest young men of the twenty-second century. His life on Earth has been spent in idle luxury, and it is only a childish whim that makes him decide one day to take an intragalactic cruise. What starts out as a safe no-thrills vacation for tourists soon goes horribly wrong, and young Shelby finds himself stranded on a mining colony in the Messina Dust Cloud --twenty-seven light-years from Earth.
