The broader SF&F category on Amazon is a high-volume Beaten Track market (~449K titles, power index ~50) with steady daily sales but brutal competition at the top. Keyword signals show hybrid blends — sci-fi horror and sci-fi thriller — rising fastest in search relevance, while pure romance crossovers dominate search volume but are already heavily supplied. Hard sci-fi as a pure subgenre sits in a relative supply gap inside this crowded parent: readers searching for rigorous science-driven fiction are underserved by indie output, which skews toward lighter space opera and romance hybrids. The sci-fi thriller vector (~45.8 score, no saturation warning) is the clearest opening for a technically grounded story with genre-thriller pacing.
