Princess Thora is the daughter of the one-time "Pretender Princess," the current Queen Rebecca. Thora is the third child of Rebecca and King Lowell, and thus has little to do.

Nothing, that is, until a puzzling series of robberies engages with Thora's mind and her sense of justice. In solving that mystery she's presented with another, and another, and still others.

Thora takes on the role of Royal Examiner. She tries to continue the improvements to the kingdom made by her mother and father while probing for the truth and seeking justice for the victims of the smartest and most devious of criminals.
