Demand Snapshot

Historical Fiction remains a high-volume mainstream category with ~290 estimated sales per day across the top 20 and a healthy power index of 58.2, but its STC ratio of 1.05 signals the market is near saturation and rewards differentiation. Mythology & Folk Tales runs cooler in raw volume (40 sales/day top-20 average) but carries a striking 47% KU share and an STC ratio of just 0.30, meaning supply is thin relative to category traffic — a classic opportunity pocket. Ancient World titles that straddle both browse nodes are best positioned to capture impulse KU borrows while benefiting from Historical Fiction’s larger discovery surface. The mythology-retelling wave driven by Madeline Miller’s long tail and successive imitators is maturing but has not peaked for indie; reader appetite for lesser-told perspectives (non-Greek, non-Roman, female-POV, non-divine protagonists) is the fastest-moving signal.
