Dawn of the Water Witch by Harold Lee Adams

Enter a world divided, where elemental magic fuels both battles and alliances. Forces of Air, Earth, Fire, Ice, and Water shape the tides of destiny, as dark magic and demons threaten to seize control. Only a united front of magic users and ordinary humans stands between survival and destruction. In the heart of this chaos is Saffra, a young woman born on the unforgiving island of Bethsheeda, raised by cruel Guild Masters who taught her to hate, kill, and obey. Though they tried to crush her spirit, Saffra's love for life endured. When her power grew beyond their control, the Guild sentenced her to death, but fate intervened. Enoch, the World Master—the greatest Magic User in existence—sensed her potential. He saved her, sparking a new beginning by taking her as his apprentice. In that moment, Saffra's life and the fate of their world would be forever transformed.
