Bill Crider wrote a handful of horror novels for Zebra under the Jack MacLane pseudonym in the 80s/90s and while Goodnight Moom may have the best cover, your enjoyment will depend upon your affinity for trashy pulp. This was a hard one to rate; I could have given this one 2 or 4 stars.
Set in some nameless, small Texas town, Goodnight Moom features a nasty redneck named Ed Leach. Homophobe, wife beater and all around asshole, this starts with Ed getting married and then promptly beating his wife because she would not give him a blow job. He did succeed, however, with his 'nasty little thing' to get her pregnant and soon enough, little Harry was born. Ed wanted nothing to do with the kid. At all. Yet, one must never spare the rod! Whether or not Harry was born 'troubled' or got that way when Ed threw him into a wall as a baby, it does not really matter.
Harry lives in his own world, never speaking to anyone. He goes to school but just sits there; he even passes first and second grade as he is so well mannered. Yet, the only thing he seems to really enjoy is killing things after causing them lots of pain. This 'yen' starts off small with cats and dogs (be ready for some serious animal foo here) but once it moves to kids, Ed decides that is enough and locks him in the basement of their house for good. The title comes from poor Harry's deranged mind; his mother used to sing to him about the moon and he kinda got mom and the moon mixed together. Being locked in the basement with only one small window, he spends lots of time looking at the moom...
Seldom have I read a book with so many deplorable characters. Ed is a first rate asshole and his 'pals' are not much better. I would have expected to feel at least a little pity for poor Harry, but not really. I will not go more into the plot; what I wrote above is not much more than the backflap blurb. On the one hand, this story moves along nicely, with one set piece to another chronicling Harry's life, warts and all. On the other hand, this is not really scary at all, even if there is plenty of gore from time to time, and really has no redeeming value what so ever. Pure escapist fun, if fun involves nasty acts of stupidity and violence, along with some asshole rednecks running around. Like I wrote at the start-- your enjoyment of this one will really depend upon your affinity for trashy pulp! MacLane/Crider knows how to write however and I have really liked the other novels of his I have read. Goodnight Moom? Glad I read it, but not sure if I will read it again.
