All the Lovely Bad Ones is by one of my favorite authors, Mary Downing Hahn.
Eleanor Duvall is the psychic in All The Lovely Bad Ones. She is also a ghost hunter.
"The happy ones; and sad ones; The sober and silent ones; the boisterous and glad ones; The good ones-Yes, the good ones, too; and all the lovely bad ones."
No, sadly it is not a movie.
