About this ranking
Hyperion (5663 mentions) and Blindsight (5232) sit ahead of Dune (4950) here, and none of the three shows up on r/Fantasy's list, where Gardens of the Moon (3986) and The Way of Kings (3461) top the chart instead - two subs sharing a genre shelf but not a single favorite book. printSF also runs cooler on the crossover hits: Project Hail Mary tops r/suggestmeabook with 1457 mentions, but here it trails Children of Time and even All Systems Red, landing at 1852 mentions well behind the harder stuff. That pattern holds throughout - Children of Time (3977) and All Systems Red (3757) beat out Neuromancer and Le Guin's Left Hand of Darkness, suggesting a readership that rates recent hard SF and quietly-plotted first-contact novels over cyberpunk touchstones or space opera doorstoppers.
