The Stephen King novel following Paul Sheldon after Annie Wilkes rescues him is Misery.
Misery was published in 1987. Paul Sheldon, a successful romance novelist, is badly injured in a car accident and taken in by Annie Wilkes, a former nurse who describes herself as his greatest fan. When she discovers that he has killed her favorite character, she forces him to write a new novel.
The story explores captivity, obsession, authorship and the dangerous relationship between a creator and an audience. Much of the novel takes place inside Annie's isolated Colorado house, which intensifies Paul's physical and psychological confinement.
Misery is sometimes remembered primarily through the 1990 film starring Kathy Bates and James Caan. The film follows the novel's central premise but is an adaptation, not the original work. Rob Reiner directed the film.
