Edgy and twisted, Natural Born Sinners is a gripping gothic occult fiction novel, with splashes of cosmic horror and dark romance. Satanos is a place of immoral release to escape the confines of the “real world”, but tourists always seem to receive more than they bargained for when they arrive upon its sinister shores. A mystifying tale of betrayal and one’s hunt for truth, all laid upon a backdrop of vile worship, this book was a page-turner, and my first read, but certainly not my last, by author J.M. Keep.
