This trilogy stands as one of the best series I've ever read -- and it will bring you into a long series of books on the people and dragons of Pern. I first read "Dragonflight" when I was 13, and it hooked me on fantasy novels in general and Anne McCaffrey in particular. If you haven't read any of her work, this is a great place to start; and, if you have read her work, you will love this trilogy. It is the epic story of how one man, believing in the tales of the past when everyone else ignored them, managed with the help of his co-leader and his brother to save the world, and make themselves legends in the process.
