William Peter Blatty, the bestselling author and Oscar Award-winning screenwriter of The Exorcist, lived a charmed life among the elite stars of Hollywood. His son Peter, born over a decade after The Exorcist, grew from an apple-cheeked boy into an "imposing young man with a quick, warm smile." But when Peter died very suddenly from a rare disorder, Blatty's world turned upside down.

As he and his wife struggled through their unrelenting grief, a series of strange and supernatural events began occurring, and Blatty became convinced that Peter was sending messages from the afterlife.

A true and unabashedly personal story, Finding Peter will remind those in grief that our loved ones truly do live on.
