A Song of Ice and Fire is a series of epic fantasy novels by American novelist and screenwriter George R. R. Martin. The story of A Song of Ice and Fire takes place in a fictional world, primarily upon a continent called Westeros but also on a large landmass to the east, known as Essos. Most of the characters are human but as the series progresses other races are introduced, such as the cold and menacing Others from the far North and fire-breathing dragons from the East, both races thought to be extinct by the people of the story.
