"Terrific. . . . Generates a haze of an altogether more serious kind: the pleasurable fog of calculated, perfectly balanced ambiguity."--New York Times Book Review

The lives of the Barretts, a normal suburban New England family, are torn apart when fourteen-year-old Marjorie begins to display signs of acute schizophrenia.

To her parents' despair, the doctors are unable to stop Marjorie's bizarre outbursts and subsequent descent into madness. As their home devolves into a house of horrors, they reluctantly turn to a local Catholic priest for help. Father Wanderly suggests an exorcism; he believes the vulnerable teenager is the victim of demonic possession. He also contacts a production company that is eager to document the Barretts' plight for a reality television show. With John, Marjorie's father, out of work for more than a year and medical bills looming, the family reluctantly agrees to be filmed--never imagining that The Possession would become an instant hit. When events in the Barrett household explode in tragedy, the show and the incidents it captures become the stuff of urban legend.

Fifteen years later, a bestselling writer interviews Marjorie's younger sister, Merry. As she recalls those long-ago events from her childhood--she was just eight years old--painful memories and long-buried secrets that clash with the television broadcast and the Internet blogs begin to surface.

"Gripping and suspenseful--[Tremblay's] ultimate, bloodcurdling revelation is as sickeningly satisfying as it is masterful."--NPR Books
