A Must Read! This masterfully written novella grabs you on the first page and doesn’t let you go. It is riveting and dark, but lightened with just the right touch of humor. By the end, you will be satisfied but want more. I can’t wait for a sequel or anything else the author, John Cassian decides to write. Not for the timid reader, Cassian pulls no punches. His protagonist killer is unapologetically sick and twisted, but strangely likable. The book is billed as a “dark erotic thriller” but it is not erotica at all. It is a fun, fast-paced thriller covering a very dark topic. It includes explicit sexual situations that are essential to the story line and are never gratuitous or extraneous. I could not be more impressed with the quality of the writing or the compelling nature of the story. “Killing Matt Cooper” has a permanent place on my favorite books shelf! Cassian successfully captured the feel of a “Criminal Minds” type television show, but transformed it into a fascinating, “Dexter” like, view inside the mind of a serial killer. In many ways I was reminded of the excellent scenes from the killer’s perspective in Thomas Harris’ classic thrillers "Red Dragon” and “Silence Of The Lambs.” Don’t miss this one, you won’t be sorry.
