"Frustrated by his father's expectation to follow in his footsteps, Prince Corin prefers sewing to sword fighting. His cousin Elinor has the eagerness for skills at arms which he lacks and, by a stroke of luck, uncovers a plot to overthrow the crown. Both cousins are befriended by a marketplace magician, whom the queen suspects is a master of the black arts and the cause of their Luck Dragon's baffling illness. When their lives and the destiny of the kingdom are at stake, Corin must choose either to trust this mysterious old man or heed the warnings of his parents"--Back cover.
