The Bright Messenger

The Bright Messenger is a horror fantasy novel by Algernon Blackwood. Julian LeVallon, born and raised alone in the Jura Mountains, is referred to a psychiatrist for care in London. But is LeVallon simply a schizophrenic with two personalities, or is he really an Elemental Being, a "bright messenger" who brings, perhaps, a new age of human evolution to the forefront? And if so, is humanity ready for a major forward leap?
