The endings of books in a series often leave the overarching plot incomplete, but progress is often made. For example, in The Hunger Games, Katniss's victory over the Capitol is half-concluded at the end of the first book, but her subsequent victory over President Snow in the second book finally brings an end to the dystopian society. In Harry Potter and the Deathly Hallows, Voldemort's return is hinted at but not fully resolved, setting up the final book in which Harry defeats him.
