Based upon the place you are in your life, God may be speaking to you about other types of stories to avoid.
For instance, I remember a time in my twenties when I felt compelled to stop reading certain secular works of mystery that flitted around the edge of darker material. Believe me, writers know that the readers' imagination can take them a step further into the story than what was actually written. We rely on this suspense tool in many of our stories, and personally I struggle at times when writing Young Adult fiction because I wonder what happens when a reader has an overly active imagination–as I had when I was young (and now too, according to my family).
I've read many a book and come to the conclusion that more so than the genres, the writer and reader must use personal discernment. If you feel disturbed in your spirit, stop writing/reading that material for awhile, evaluate, and sometimes you might come back with a fresh perspective.
At times there may be another reason why to give a particular type of fiction a break. I usually do not watch movies, television shows, read books that have the same genre as my work in progress. For a 'pantser', writer who writes 'flying by the seat of their pants', that is almost a sure way drive the final nail in my coffin of inspiration–and I have a dead work on my hands.
Currently, I am editing a fantasy epic adventure. That means that the story is set in another world ('fantasy'), the characters are traveling throughout (think 'Eragon' or 'The Hobbit' for epic examples), and hopefully, the story will be an adventure for the reader as it is for my characters.
And currently, I am writing a medical suspense with a dabbling into the future of medical advancements and the woes of a troubled mankind...the quandary of balancing ethics when science is caught in a minefield–determining the value of human life.
Continue with me tomorrow on this subject as I discuss how fantasy reading and writing is a unique field to me as a writer.
