Rebellion has broken out in the Kingdom of the Elves, and Vicky's friend, Aurelia - now Queen - has been deposed and imprisoned. Once again Vicky is called upon to help. Magically transported to the kingdom, Vicky helps free her friend but learns that overcoming the rebel elves is dependent on finding a rare gemstone that holds the magic that all elves once possessed. Called the Magic Crystal, it was hidden centuries ago in a land far away that Vicky recognizes as Ancient Egypt, but if the rebels find it first Aurelia will have no chance of regaining her throne. Vicky, Aurelia, Ephelia, and Andron must therefore undertake a perilous mission, the success of which will rely on Vicky's magical powers. Aided by dragons and a strange desert people, the four friends eventually travel through space and time to Tutankhamun's Egypt, a land also riven by strife and one in which the rebel elves are already present. There, the friends face further obstacles: a battle on the Nile; a major conflagration; capture by the rebels; and a life-threatening trial in the Egyptian Underworld. And even if they locate the Magic Crystal can they keep it out of the hands of the rebels - and how will they be able to return home?
