The White Dragon Dragonriders of Pern Vol 3

When Lessa chose a dragon over her birthright, the hold she was to have inherited passed to Lord Jaxom instead. But Jaxom then muddied generations of Pern tradition by impulsively Impressing Ruth, the small and singularly unique white dragon, as a child. From that moment on, the debate has raged. Is Jaxom now a dragonrider, or a lord holder? All anyone agrees on is that he cannot be both. But perhaps it is all academic anyway, for no one expects Ruth to survive.

But Ruth not only survives, he thrives. With Jaxom on the cusp of adulthood, the thing the pair most desire is to fight Thread side-by-side with the larger dragons. Jaxom knows what his dragon is capable of, and now that he is--mostly--grown, he is determined to buck tradition. Fortunately, a teenage rebellion may be the key to both Pern's salvation and winning the woman of his dreams.
