The Secret of the Ninth Planet

How it begins

On the morning that the theft of the solar system's sunlight began, Burl Denning woke up in his sleeping bag in the Andes, feeling again the exhilaration of the keen, rarefied, mountain air. He glanced at the still sleeping forms of his father and the other members of the Denning expedition, and sat up, enjoying the first rays of the early morning. The llamas were already awake, moving restlessly back and forth on their padded feet, waiting for their tender to arise and unleash them. The mules were standing patiently as ever, staring quietly into the distant misty panorama of the mountains. It was, thought Burl, a dim day, but this he supposed was due to the earliness of the morning.
