Recommendation: "I Know He Loves Me (He Just Has a Funny Way of Showing It)" by James Newman

Found in the huge anthology Midnight in the Pentagram edited by Kenneth W. Cain, James Newman's story concerns the aftermath of an exorcism, and the effect it has on the protagonist, at that time fifteen years old.  Far from the happy ending implied by most possession tales, Newman suggests what would follow is a mélange of post-traumatic stress, isolation, and, to some extent, longing, all told in elegant prose with mounting unease.  It's a story I wish I had written.
