In the distant future, long after Earth's fall, the Seven Stars colony thrives under a strict neo-Christian regime that dictates everything from belief to identity. Asher Deka has always followed the rules - a disciplined soldier, a dutiful son of the faith, and a man who has learned to hide the truth of who he is.

When whispers of rebellion spread through the colony, carried by those who claim the Mark of the Beast as a symbol of liberation, Asher's carefully constructed life begins to fracture. His loyalty wavers. His questions multiply. And time spent with a childhood friend, someone who awakens feelings he's been taught to fear, forces him to confront the desires and grief he's long buried.

As the resistance grows louder, Asher must choose between the world that shaped him and the future he might finally claim for himself.

Concurrently, Revera Taylor, a trans woman whose smuggling career evolved into espionage, embeds herself within the Seven Stars under a carefully crafted new identity. Seeking to uncover the regime's most closely guarded secrets, she finds herself drawn into the underground resistance beginning to reshape Asher's world.

Blending queer resilience, dystopian tension, and the fierce tenderness of found family, Good and Faithful Sinner is a story about breaking silence, reclaiming joy, and daring to imagine a life beyond the boundaries of belief, following multiple voices whose lives collide at the heart of the rebellion.
