Book 2 in the Oz trilogy!

Peace has been restored to Oz. The fallen
Witch, Lynessa, and her sister, Zina, are fading into memory like a bad dream,
soon to be remembered only in tales meant to frighten children. But there is one
witch that still draws breath in Oz and she has not forgotten the power of her
masters or the evil that they left behind. Soon the people of Oz will face a foe
more frightening than any enemy that has come before... The Warlord of Oz has
arrived!
