Dragonfire and Time

An angry dragon demands justice of the king.

Mae, a royal wizard, is assigned the task:  the dragon had metted out her own justice, burning a thief with dragonfire, but she had seen him since, whole and sound, and this she will not tolerate, so Mae must put an end to it.

Mae goes to discover the truth of this before the dragon leaves its lair to extract her own justice.  And in her search of the spring festivities, learns more secrets than the dragon had even guessed of.
