I read the first three books of this series: Dragonflight, Dragonquest, The White Dragon.
This is a fun series that takes place on another planet. The people originally arrived on the planet in space ships but over hundreds of years have lost their technology.
A small percentage of the population ride and care for dragons which were genetically created in order to destroy a microorganism they call Thread that rains from the sky. In the beginning of the series, it has been 400 years since the last fall of Thread. The people of the planet Pern don't believe that Thread will fall again. They are beginning to wonder what purpose the dragons and their riders serve. One dragonrider believes that Thread will fall again and has spent time reading ancient writings to determine when the fall will come.
The first three books cover about 20 years. There's romance, politics and discovery. There are 23 books in the series from what I can tell. This will definitely be a good series to read as filler between heavier and more serious books.
