Wicked Light — Scott Skipper

A successful author loses his grip on reality, his marriage, and his life as weird and even impossible things begin to happen to him. He struggles to discover where it is coming from and to keep from slipping over the brink of sanity. As the layers peel from the kernel of truth, he grasps at whatever or whoever can pull him back from the abyss. Is the source of his torment human, paranormal, or is it himself?
