We got stuff for any brow level you want. As well as many, many easter-eggs for sci-fi & fantasy nerds alike. Galactic horror: I'll leave the fully fleshy nature of that for you to discover a few chapters in, it's better that way. Fun with Letters: Silly little anagrams, and silly little acronyms.

Memory of Heaven

Love is not illegal in this universe. It is simply not allowed to exist. When an Overseer of Reality falls in love with a girl meant to die, causality begins to fracture—and the universe starts preparing to erase them both. *** In a universe governed by function, efficiency, and cosmic law, love is an anomaly no system can quantify. Fitran is an Overseer of Reality—an executor of balance tasked with maintaining causality across worlds. He was never meant to choose, hesitate, or care. Rinoa is a fractured soul, rewritten across eras and timelines, engineered to become a necessary martyr—a sacrifice required to keep reality stable. Together, they are a contradiction. Every time they hold hands, probability falters. Every time they separate, the universe stabilizes. As ancient machine gods awaken, angels descend to enforce order, and the Void turns its attention toward Earth, one truth becomes unavoidable: The universe does not fear war. It does not fear extinction. It fears a love that breaks meaning itself. This is not a story about saving the world. It is a story about choosing love in a reality that would rather collapse than allow it.
