The Dark Tower VII: The Dark Tower is a fantasy novel by Stephen King, and the seventh in the Dark Tower series. Jake Chambers, his billy-bumbler, Oy, and Father Don Callahan storm the Dixie Pig restaurant in New York City, fighting vampires to free Susannah Dean. Callahan gives himself up so Jake can get to Susannah, who was taken by the low men along with her alternate personality, Mia. Susannah and Mia started out in the same body, but now Mia is her own being and is pregnant. Susannah watches as Mordred, a human who can morph into a spider and is the son of Roland Deschain and the Crimson King, is born. After wounding Mordred, Susannah escapes and meets up with Jake and Oy. Roland Deschain and Eddie Dean are in Maine, convincing John Cullum to start the Tet Corporation. The corporation will do everything in its power to protect the rose, which represents the Dark Tower in our world. When they return to Mid-World and the ruined city of Fedic, they join up with Jake and Susannah and the ka-tet continues through the tunnels under Fedic searching for a door to Algul Siento.

Once the gunslingers arrive at Algul Siento, Roland Deschain, Susannah Dean, Eddie Dean, and Jake Chambers they work with Ted Brautigan, Dinky Earnshaw, and Sheemie Ruiz to free the breakers, a group of telepaths who were captured by the Crimson King and are breaking the beams that hold the universe and Dark Tower together. Eddie Dean is killed after this fight. Roland and Jake travel to Maine in 1999 to stop Stephen King from dying after he is hit by a van. However, Jake dies in his place. Roland buries Jake, and then travels to New York to visit the Tet Corporation. When he returns to Fedic and meets Susannah, they continue towards the Dark Tower. They rescue Patrick Danville from a vampire, Dandelo. Susannah decides to quit the quest for the tower, choosing a life with alternate versions of Eddie and Jake. She leaves for an alternate version of New York.

Mordred attacks, but Oy saves Roland, dying in the process. Roland and Patrick get to the Dark Tower, where the Crimson King awaits them. The King throws sneetches, or flying grenades, at them. They hide behind a rock and steel barrier to buy time and come up with a plan. Patrick draws a picture of the Crimson King and them erases it, erasing the King out of existence. Roland climbs the tower, but is transported back to the beginning of his journey, realizing he is doomed to repeat it.
