One of the problems of Jewish novels is that the editor/publisher will edit out any “buzzwords”, even if they are used by frum yidden.
For example, a friend of mine (a well known jewish author) has told me that he had to get the concept of “a girl who is a friend” across (in a platonic sense), without mentioning the boy & girl were friends.
This is without the controversy caused by some rabbonim/authors who decide to go the “Israel Trade Co.” route, V’Hamaivin Yovin.
