Wings of Fire
The Wings of Fire series focuses on the adventures and endeavors of young dragons ("dragonets") to fulfill or stop prophecies and make their world a better place. There are two continents filled with dragons in the world of Wings of Fire, and these dragons are split into ten tribes based on their biological characteristics - on Pyrrhia, there are the MudWings, SandWings, SkyWings, SeaWings, RainWings, IceWings and NightWings, and on Pantala, there are the SilkWings, HiveWings and LeafWings. With a few exceptions to each rule, the dragon tribes live separately from one another in a habitat suited to their needs, and are ruled by a queen. There are also humans in the world, usually called "scavengers" by the Pyrrhian dragons and "reading monkeys" by some Pantalan dragons, though humans are usually eaten and considered inferior animals. Despite this, at times the books explore the relationship between humans and dragons.
