What else is there to do when the world is coming to an end?

The intergalactic athletic competition had just begun, and Shaun Sili didn't even know about it when fast-talking trader Zeth Tristotha found him herding sheep on the high-gravity planet Sobillon. But Zeth knew Shaun would make a discus thrower--maybe the best in the galaxy. Once aboard Zeth's ship the Vulcan Adventurer, Shaun is on the way to high adventure among the stars--on the water-covered planet Droth, where the strange underwater life offers stranger perils, and on the planet Pevoria, site of the Olympics, where Shaun must compete not only with his fellow athletes--but with mortal danger!
