The broader Science Fiction category is a high-volume, competitive mainstream market with ~449K titles and a power index of 49.6, signaling healthy but crowded demand. Romance crossover keywords (sci-fi romance, scifi romance, science fiction romance) are scoring at the top of all keyword signals, indicating the fastest-rising reader appetite in the space right now. Horror-adjacent sci-fi is rising steadily at mid-tier scores. Pure military sci-fi as a standalone keyword is not in the top signals, meaning it must borrow demand from adjacent rising categories to break through.
