IT is the 22nd book published by Stephen King. It was his 18th novel, and the 13th novel written under his own name. The book was released by Viking on September 15, 1986. IT follows the story of seven children from Derry, Maine who are stalked and terrorized by a supernatural entity they know as "It." The creature has the ability to disguise itself to stalk its prey, and uses their greatest fears against them. It often appears in the form of an evil-looking clown, and prefers to prey on young children. The novel alternates between two time periods, interweaving the story of the children and the adults that they will eventually grow into. Common King themes are woven throughout the novel, including the notion of the power of memory, traumas experienced in childhood and their effect in later life, a small town with dark secrets, and triumphing over evil through trust and sacrifice.
