All the Weyrs of Pern by Anne McCaffrey

The dream of generations of Dragonriders draws within reach as, with the aid of an intelligent computer, the possibility of destroying the devastating phenomenon known as "Thread" becomes a reality. Having exposed Pern's civilization to technology in Renegades of Pern McCaffrey proceeds with her customary skill and humor to explore all the ramifications of culture shock. Despite some weaknesses in plot and an odd notion of time travel, the latest novel in a popular series will not lack for readers. Especially for libraries owning the previous Pern titles.
