Moonfallow Series
Anaria keeps her promise to her Shaman mother and is whisked from her home planet to Dilunar, where the people of the dangerous moon live underground. The leaders are angry and disappointed  she has come instead of her mother. They believe Anaria is not a properly trained Shaman and will be unable to move their people to the safety of another moon.
Leion does not agree with his fellow leaders. He befriends Anaria and together they design a plan to move the people. If they fail everyone on Dilunar will die.
