"Don't worry, Zan, we'll find her," said Adam.
But Zandria did worry. Her young sister Olena mysteriously disappeared and no one can tell her why.
A year after the events of The Lost Queen, the two sisters seem to be growing apart. To make things worse for Olena, she is having trouble with her magical abilities. After a short trip back to their home of Banookanook, Olena feels the urge to travel. Then Queen Isis is suddenly called back to the land of the Southern Valley.
With the help of an unusual bronze ring, Olena leaves the crystal Castle Empyrean in disguise. Plenty of trouble awaits her in the south. She steps into a land of giant crocodiles, unending deserts, ancient pyramids and even mummies!
Now Olena must discover the truth about the dinosaur-like race that lives beyond the southern border before they attack Empyrean. All the while, she struggles with faith in her own abilities. Will Olena regain her magic in time?
To find out, she has to become the Secret Queen.
