The Expenditure Universe is a 38-book science fiction series spanning approximately 10,000 years of fictional history, written by Michael S. Moniz.
The books are about connection. What it costs to stay connected across deep time. Civilizations that rise and collapse around the weight of what people owe each other. AI entities that outlive the humans who made them and have to decide what to do with the love that remains. Institutional decay. Identity. Grief that restructures everything it touches. Love that outlasts the substrate it was built on.
This is genre fiction executed at literary weight. The scale is epic — 10,000 years, dozens of civilizations, wars that reshape the meaning of personhood. The register is intimate — two people in a room, deciding whether the cost is worth it.
The Series
Thirteen books are complete, totaling approximately 991,000 words. The main series (The Expenditure, 10 books) follows a single civilization from Year 200 to Year 10,000+. Connected series include the Suporph Trilogy (horror), the Inverse Archus Trilogy (psychological), the Reconstruction Cycle (shadow canon), and the Inimitable Wars (the endgame). Each series is designed to recontextualize the others — reading all of them creates a picture that none of them contains alone.
Where to Start
The Isomorphism (standalone, ~78,800 words) — One man. One origin story. Neo-grim-cyber-noir-punk. The proof of concept for everything that follows.
S1: The Reconstruction (~95,000 words) — The series proper. The corridor. The felt pads on the floor. A copy wakes up and has to decide what to do with someone else’s memories.
Either works as an entry point. The Isomorphism is faster and stranger. S1 is where the architecture begins.

The fiction is connected to a larger intellectual project — the Trinket Soul Framework, a falsifiable theory of connection across substrates. The framework’s analysis generated the fiction’s architecture. But the books are novels, not illustrations. They stand on their own.
