''Song of Susannah'' is Book VI of Creator/StephenKing's [[DoorStopper Epic]] {{Fantasy}} series ''Franchise/TheDarkTower.'' Pressed for time, Callahan, Jake, and Oy are hot on Mia's trail as she manipulates Susannah into going to New York in the year 1999. Can they prevent Mia from giving birth to [[AntiChrist The Chap]] who will help his father, [[OmnicidalManiac The Crimson King]], [[TheEndOfTheWorldAsWeKnowIt destroy the Dark Tower]]? Meanwhile, gunslingers Roland and Eddie travel to 1977 Maine in search of bookstore owner Calvin Tower, and end up meeting Stephen King himself.

Followed by ''Literature/TheDarkTower''.
!!''Song of Susannah'' provides examples of the following tropes:

* AuthorAvatar: Stephen King appears in the book as himself. Roland and Eddie have to talk him into continuing the ''Dark Tower'' books, since the stability of the universe depends on it about as much as on the Beams and the Rose.
* BadassBystander: John Cullum, a fairly ordinary store owner, gets mixed up in the shoot-out between Roland and Eddie, and Balazar's men. He sides with the ka-tet without just about any hesitation, helping them survive the ambush, providing them with transport, and inviting them to his home afterwards. Lastly, he points them in the direction of [[AuthorAvatar Stephen King]] when Eddie worries about not being on time to both talk to him and save Susannah, saving them a significant amount of time.
* BadGuyBar: The Dixie Pig is full with the [[BigBad Crimson King's]] soldiers.
* BodyHorror: The Grandfathers in the Dixie Pig, a very high-ranking type of Vampires, are described as incredibly grotesque-looking complete with monstrous teeth.
* DemonicPossession: Mia isn't simply a split personality, she is a spirit who invaded Susannah's body to give birth to the Crimson King's son.
* FetusTerrible: Susannah reasonably suspects that this is what Mia's son will turn out to be, considering it's the son of the Crimson King.
* TheUndead: The Dixie Pig is full of various classes of Vampires.
* ToServeMan: Though mercifully brief, Susannah catches a glimpse of the Grandfather-type Vampires feasting on a baby.
