Space opera includes adventure stories usually set in outer space or on another planet. They are sweeping sagas often involving interplanetary politics or family conflict. The category shares characteristics with military science fiction, but is not as focused on the military effort, and is generally considered more romantic in tone. Stories that are similar to the Star Wars movies fall into this category.
The narrative can unfold over several books. Well-known writers include C.S. Friedman and Frank Herbert.
