After the defeat of one Wicked, the other Witches of Oz prepare for vengeance in this second book of the Ages of Oz series!

Glinda and her friends have successfully vanquished Aphidina, the first of the four Wicked Witches. But her task is far from over.

With the fate of all of Oz hanging in the balance, Glinda struggles to locate a mysterious teacher called Mythra, who is the only one who can guide her in reaching her mystic potential and becoming the powerful Sorceress she is destined to be. While Glinda searches far and wide for her mentor, the fiery-spirited Locasta finds herself undertaking an equally important search--for the Elemental Fairy of Lurl, and the means by which to destroy the second Witch, Marada, Wicked Warrior of the North.

Surprising discoveries await both Glinda and Locasta. Great dangers threaten, formidable enemies lurk, and startling secrets abound. Glinda, Locasta, Ben, and Shade bravely continue their mission teaming up with some very welcome--and very unexpected--allies along the way. Together they prove that there is no hope for the future if one is not willing to learn from the past.
