A Head Full of Ghosts by Paul Tremblay
Synopsis:
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 descent into madness. As their stable 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. With John, Marjorie s father, out of work for more than a year and the medical bills looming, the family agrees to be filmed, and soon find themselves the unwitting stars of The Possession, a hit reality television show. When events in the Barrett household explode in tragedy, the show and the shocking incidents it captures become the stuff of urban legend.
