The Great Everlasting — Ray Johnson

Dan Harrington seemingly had everything: a prosperous business, a beautiful redheaded wife, a magnificent home in the towering Sierra Nevadas, and expensive luxury cars. But he also had a disintegrating marriage and skull-cracking headaches. He was midnight plagued by haunting nightmares, murky incubuses that told him to go to the wilds of Montana. Once in Montana he meets a gorgeous Indian woman who claims to have been born in 1842. The radiant Indian woman warns Dan of impending danger, coming at the hands of his wife and her lover. Is the Indian woman a clever temptress, only after his wealth, or a captivating wraith that was sent from The Great Everlasting to warn him?
