Dumped by the Prince, Crowned by the King

In the elven kingdom, Elana is betrayed by her sister Serene and fiancé Prince Caelum. They poison the king; Serene leaves Elana's mother in a coma. Elana turns to King Celepharn—Caelum's father. She saves him from a monster attack, wins his trust, and becomes queen. At Caelum's wedding, Serene sees Elana return—not as her victim, but as her stepmother. Revenge begins.
