Ozma of Oz (2010) #3

Tik-Tok, the clockwork man, defeats the Wheelers and learns their hidden secret. But that's no help in battling the army of Langwidere, a princess with thirty disembodied heads. Langwidere intends to cut off Dorothy's head for her collection-unless the Scarecrow, the Tin Woodman, and Ozma can rescue Dorothy. But how can Dorothy's Oz friends cross the Deadly Desert to save her?
