Randor's Moon

Randor Delphin, shy teen prodigy, bio-scientist, and total nerd, lives a lonely, orphaned life on the planet of Malloran, a colony of the now-dead Earth. Malloran has been at war with the neighboring world of Falanar, a warrior planet, but their differences will be set aside if aid is given, as a plague of unknown origin has broken out, and only the scientists of Malloran can help. Accompanying Randor is Minnara, the daughter of the rulers of that world.
As total opposites in character, they don't get along at all, and to make matters worse, their ship veers off course and crash lands on a distant moon. Once there, they learn that they need each other in order to survive against the predators of that world, those that are animal, and those more than animal.
