The Exorcist — William Peter Blatty

The inspiration behind one of the most successful horror movies of all time!

Chris MacNeil -- adored film star, divorced single mother -- has come to Washington, D.C. to finish a movie. Swept up by the demands of her busy, flourishing career, Chris is blind to the subtle warnings that a dark, malevolent presence has invaded her comfortable townhouse. Powerful and cunning, it is taking possession of Regan, her 12-year-old daughter. Every avenue of help leads to a dead end. Now hope lies only in a doubt-ridden priest and his fragile elder... in a terrifying battle with an obscene, unspeakable evil that must end in victory...or madness and death.
