It sounds like this writer's major themes are quite similar to those of H.P. Lovecraft, whom many credit as the originator of modern horror fiction. Lovecraft himself was averse to fantasy, but not to the fantastic -- he had the notion that there might be, in the world, things stranger than are dreamt of in our philosophy... and that some of those things might be malign, or simply dangerous because they did not perceive us, any more than a man perceives a beetle as he carelessly steps upon it. Perhaps, he suggested, we'd be better off focusing on enjoying the mundane, rather than poking our noses into corners of the world where things older and more powerful than ourselves might be slumbering.
