Tuck Benedict is disappointed to learn that his hoped-for reunion with his father must be postponed. Colonel Benedict has spent years troubleshooting on Mars and Venus for the Security Commission. His leave has been cancelled. He’s been dispatched to Titan, home to unruly rubidium miners.
The colonel invites Tuck to join him on his mission to Titan, but Tuck fears delay in reporting to college could cost him his scholarship. Then … luck puts Tuck in a position to save his father from a mail bomb. Afraid that the assassin might succeed if Tuck is not there to protect his father, Tuck changes his mind. School must wait until Tuck returns from the mining colony.
