YA-Set just prior to Dragonflight, Masterharper details the life, loves, and heartbreaks of Robinton, Pern's most beloved harper. Readers follow him through a childhood filled with rejection and neglect by his Mastercomposer father, the loss of his wife, the death of his best friend, to his becoming Masterharper of Pern. This is McCaffrey at her best, combining excellent writing with vivid settings and detailed, fully fleshed-out characters. The book would be best read after Dragonflight (1986) and Dragonquest (1979, both Ballantine), but can stand alone.
The planet Pern has been colonized for centuries by humans. When humans first settled on this world, they did not take notice of its sister planet, which had an indigenous life form that attempted to land on Pern when it came within reach. These silver "threads" fell in a destructive wave on the temperate lands of Pern once every 200 years, destroying all life they encountered. To combat this menace, the inhabitants of Pern developed a species of dragon that could burn these threads out of the sky before they touched down.
