Rage (written as Getting It On; the title was changed before publication) is the first novel by Stephen King published under the pseudonym Richard Bachman in 1977. It was collected in 1985 in the hardcover omnibus The Bachman Books. The novel describes a school shooting, and has been associated with actual high school shooting incidents in the 1980s and 1990s. As a result, King has allowed the novel to fall out of print.
