Avi K Torah values are the values of a Torah lifestyle. How the children speak to the parents. Clean language. Belief in Hashem. Appropriate interactions between males and females. Etc etc. Any non Jewish novel or story book I’ve come across (BH I’ve only had to read a few) has had problematic hashkafos.
Science books are a different story with a different problem. But that problem can be resolved. Novels are just tried. For every good thing you can learn from them they desensitise our holy sensitivities in other areas.
