Shanji

the long version

On the planet Shanji a ruthless Emperor rules a subjugated people. Kati, raised by the lower caste Tumatsin, is taken captive by the Emperor's troops, but saved by The Searchers, who see her as the promised Empress of Light, who can control the hot light of creation. But Kati's psychic powers can destroy a planet or star, and could be beyond everyone's control. She must decide how to use her powers when there is a planetary invasion from afar, led by a powerful Empress Kati thought was her friend and teacher. The barbarian girl must take charge of her own destiny, not only for herself but for Shanji and its neighboring worlds. Born with the heritage of two races, she must rule both of them.
