House of the Moon
by C. M. Barrett
In the deep desert of Etrenzia, a young scientist is kidnapped. Her sister, Serazina, Heroine of Oasis, braves giant snakes, sandstorms, and invisible enemies to try to rescue her. Phileas, Guardian of Oasis, who has fallen in love with her, shares her ordeals. Neither of them knows they are being lured to the desert for a purpose far more sinister than their worst fears.
