How do you know if it's good satire if you don't have trusted readers to give feedback? It's nearly impossible to judge the quality of your own work. I notice that the book was "created with the assistance of AI tools"... hopefully you didn't interpret AI's syncophancy as a signal? Part of writing for an audience is engaging with that audience to understand how they perceive the work. If you don't have beta readers from an existing network (writers' workshop, etc), they're available as a paid service.
