The Lost Princess of Oz by L. Frank Baum - Ozathon24

The eleventh Oz book begins dramatically – Ozma, the lovely and beloved girl ruler, has disappeared! Dorothy sounds the alarm because she knows Ozma would never intentionally cause worry, so she must have been stolen. The Magic Picture, Glinda’s Great Book of Records, and the Wizard’s black bag of magic tools are also missing, preventing anyone from using magic to find Ozma.
