Judge. Tracker, #3

Never admit to seeing ichur, the silvery residue of magic spells. Not if you want to stay under the radar of the Councillors of Convane. Misty Locke intends to protect Dallas from mages discovering his secret of using ichur while he attends the academy in Dead City to become a judicator. But before they even reach the academy, she has to protect the tracker mares from a runaway wagon. Then protect Dallas and the mares from thieves intent on stealing both trackers.
Which leads to her arrest by the rider of a very large black and yellow dragon called Tema, because he witnessed her attacking citizens of Convane. Judge continues the adventure after Rider and Guard ended, including mages, dragons, tracker horses and magic spells.
