Dean R. Koontz wrote dozens of genre paperbacks throughout the 1970s and early 1980s before he became the eternal bestseller king he's been now for over 25 years. Me, I haven't read a book of his since the first Bush Administration, and even then I quickly tired of his formula after just three novels. In fact, one of his books, Midnight (1989), has what I consider one of the worst endings I've ever read in a book written by an adult man writing for adult readers: the protagonist, after defeating some sort of science-gone-wrong evil, barges into his estranged teenage son's bedroom and proceeds to smash all his heavy metal records (revised to CDs, in the paperback reprints in the ensuing years), then forces him into an embrace. All's well that ends well, amirite? Man, as a teenage Jersey metalhead, I was all like "Fuck. You." to Mr. Koontz. Still: he got some pretty decent vintage covers, even for his various pseudonyms - Demon Seed (Bantam 1973, art by Lou Feck) and The Flesh in the Furnace (1972) definitely the high points.
