All The Weyrs Of Pern (The Dragon Books) by Anne McCaffrey

AIVAS has been found and provides the people of Pern with access to their history and all the technological knowledge they had lost over the turns (years). AIVAS has also promised to rid Pern of thread but to do that they will have to relearn a lot of the scientific knowledge and advanced technologically they lost. But some of the Craftmasters and lord holders are not impressed with the changes to their society and oppose all the efforts going as far as sabotage.

This is one of my most read books there is not much action in it but I really like the interaction between the characters. I particularly like the interaction between the characters and AIVAS People of a low technological society trying to understand Artificial Intelligence and how to interact with it.
