Demigod Magic — T. Jackson King

Janie the White witch is faced with new challenges due to her demigod status and her access to God Power magic. The Greek goddess Nemesis, who punishes mortals who show arrogance before the gods, attacks Janie. The Norse gods Thorr and Odin appear to help her defeat Nemesis. As do the local vampires led by Master Brioc. Many adventures follow. Then Mother Earth captures her essence with a demand for her to reverse climate change. And no, Janie is not an eco-freak. But when the Mother Goddess of Earth dumps her green earth magic on you with a demand to 'do something' to stop her being poisoned and deforested, well, what's a witch to do?
