Why this book?
Would we even be discussing this topic if not for William Peter Blatty’s classic novel of demonic possession? This book, inspired by the real exorcism of a Maryland boy in 1949, terrified readers when it was published in 1971. It depicts a young girl in Georgetown who may or may not be possessed. The troubled mother eventually enlists the help of a priest, and the ultimate battle of good and evil ensues. Blatty went on to write the screenplay for the equally traumatizing film and won an Academy Award for his efforts. What makes this book essential reading for preparing you for demonic possession is that it shows the step-by-step process of possession, so that you can spot the early warning signs. If you or a loved one notice your bed moving on its own, don’t run the gamut of psychological evaluations: consult your nearest self-loathing priest immediately.
