More books arrive! Paperbacks. Whoever printed and bound them puts little value on the aesthetics of outer appearances; the covers are off-white like the pages inside them.
The first book is an aggressively mundane (though comically written) tale about subsistence farmers in a fantasy setting with technology on par with Golarion's. The male and female leads keep their heads down through political turmoil and dragon-slayings; the drama in the story mainly comes from the psychological distress inflicted on their entire extended family from having to hurry to get the planting done in time. One gets the impression in reading it that the setting is based on a well-known legend typically told from a different vantage point, but knowing the exact details there isn't really necessary to enjoy it (if you're the sort of person who enjoys the sort of thing).
The second book centers on a LG teenage boy who vanishes from their industrialized society (mentioned in tantalizing passing) and finds themself falling out of the sky in a much more primitive one--by far less technologically advanced than Golarion--as a burly man with 20s in all their physical stats. Injured from the fall, he's nursed to health by a society of CE raiders tell him that he's their prophesied hero who'll elevate them beyond their humble means. At first horrified by their slavery and brutality, the book goes into great detail about how being lovebombed and worshiped corrupts him to Evil. (And into detail about how a messiah-figure obsessed with discipline and drill turns disorganized and factional raiders into a more Lawful fighting force, all without invoking the terminology of Alignment at all). He takes on a harem to share his phenomenal stats with future generations, and unites various clans and conquers small polities over twenty years while preparing in earnest for world conquest. He . . . helps them industrialize somewhat beyond the point of Golarion! The book goes into detail on the science of gunpowder, steam engines, and telegraphs! After years of war, his armies clash against a great walled city that'd been set up as a threat since the start of the book. They're led by a genius inventor and strategist themself, a woman who he becomes obsessed with. After finally breaching the city and enslaving the populace, he takes her for his harem--determined to make her his.
The book then abruptly shifts perspectives, starting again where the main character falls from the sky, but this time as a young girl and in a different place. She wins the respect of the walled city with her technical and philosophical knowledge, and becomes beloved by them--showing them a more egalitarian way. When the raiders become an increasingly salient threat, and diplomacy fails, she helps them prepare to defend the city, but it isn't enough. She considers resolving to kill herself if she's captured, but can't bring herself to do so, instead resolving to try her best to do what good she can while looking for a path to escape and survive. But when she's taken as a slave, she realizes that her captor is an alternate version of herself. The rest of the book shifts perspectives frequently as the male lead struggles with resurgent guilt and despair--brought to earth, his power fantasy interrupted--and details how he attacks the female lead in anger. Meanwhile the female lead tries to lead him towards the light, all the time trying to keep the flames of hope alive in her own heart and doing what she can to help the other harem girls. Eventually, though, they both give into despair and live a miserable codependent life on each other; ruling the world empire joylessly without the resolve to steer events in any particular way until it ossifies and tears itself apart.
Abandoning family and other obligations, they turn to subsistence farming and slowly they find some small measure of peace.
