Collects Oz: Reign of the Witch Queen #1-6.
*Dorothy Gale has twice saved the people of Oz from the evil machinations of her own family: first from her power-mad twin sisters, Zinna and Lynessa, and then again when her mother, the arch-witch Zamora, returned from the dead to enslave the Realm of Hope. With the help of her allies–Thorne, Scarecrow, Smynth, Adraste, and Toto–Dorothy prevailed and realized her own growing magical power.
Yet their victory is short-lived.
When Zamora and Warlord return with new allies to threaten the Emerald City itself, Dorothy and company must take the attack to their enemy, concocting a desperate plan to separate Zamora from her most powerful allies. *Source: zenescope.com
