According to Wikipedia, the Dark Tower is a series of eight books that combines multiple genres including dark fantasy, science fantasy, horror and Western. It expands on King’s multiverse and links together many of his other novels. The story centers on a “gunslinger” and his quest to protect the Dark Tower, a mythical structure which supports all realties. The inspirations for the series includes the poem “Childe Roland to the Dark Tower Came” by Robert Browning as well as The Lord of the Rings, Arthurian Legend and The Good, the Bad and the Ugly. The movie is a continuation of the series and takes place in both modern-day New York City and Mid-World, Roland’s Old West-style parallel universe. Roland is on a quest to reach the Dark Tower in End-World and reach the nexus point between time and space that he hopes will save humanity from extinction. It is a sequel to the events that take place in the books.
