THE SECRET of the MARTIAN MOONS THE SECRET of SATURN'S RINGS

_The Secret of the Ninth Planet_

On the day that the theft of the solar system's light begins. Burl Denning is with an archaeological expedition in the Andes, only a few miles from the source of the "disturbance." Within hours the United States Air Force has ordered the expedition to investigate the strange phenomenon that is causing a dimness and a drop in temperature throughout the world.

This is the start of a fantastic adventure that eventually takes Burl, a high-school senior, on the first circ.u.mnavigation of the solar system.

On planet after planet, he and the crew of the _Magellan_, a gleaming, powerful, and virtually untested s.p.a.ceship, discover the weird trappings of a brilliantly-designed Sun-tap station. Each planetfall brings unexpected hazards, as the ship draws closer and closer to solving the mystery of the theft.

The author has based his story on science fact. Researchers are actually at work on the possibilities of just such a circ.u.mnavigation, and on another surprising theory brought out in this book.
