The people of the Fire, the Blesa, led by their Queens, have ruled the Island of Alfeyju and oppressed the Driva, the people of the Ice, for more than sixteen generations. With the Drivian King in hiding, and little hope on the horizon, the Driva look to one person to save them from the vile Blesa: the Diviana. According to legend, the divinely gifted Diviana will one day overthrow the Blesa and restore the Drivian King to his rightful throne.
But with the search having lasted for more than four hundred years, will the Diviana ever come to light?Willow is the slave of the Raskpil family. Bought at the age of four, twenty years have passed since her life irrevocably changed.

Will she fail as all before her have?Will she rise to the challenge and become stronger after passing through the flames?
