The White Dragon by Anne McCaffrey

 Never had there been as close a bonding as the one that existed between the daring and adventurous young Lord Jaxom and his extraordinary white dragon, Ruth. Pure white and incredibly agile, Ruth was a dragon of many talents, though almost everyone on Pern thought he was a runt that would never amount to anything. But Jaxom knew better, knew he could teach his dragon to fly and to destroy the deadly silver Threads that fell from the sky. Disobeying all rules, Jaxom and Ruth trained in secret. Their illicit flights seemed but a minor disobedience-- until they found themselves in the path of danger and in a position to prevent the biggest disaster of all! From Goodreads

This is my favourite book of the three first book in the Pern series. I like the way Jaxom is maturing and trying to find out who and what he is. But as the title suggest the main character is The White Dragon Ruth. I enjoy reading about Ruth and seeing how different he is to the other dragons and he knows so much more than them. It seems like he is a lot more intelligent than the other dragons in the sense that he is not so controlled by feelings but then he is also described as asexual so he does not react when the queens and greens get ready to fly.
