The Mouth of Abaddon

A storm cracks open an old monastery. A word escapes. People vanish mid-sentence.

When a hillside collapses beneath a remote monastery, linguist Dr. Elijah Cross is called in to translate the marks carved into a sealed stairway. The locals whisper a single word, "Abaddon," like a dare, like a joke, like a story that cannot hurt them. Then the laughing stops. Coats and boots are left behind. Voices fail. Shadows learn to listen.

With Sister Marianne Duval and the hard-edged pragmatism of Dr. Priya Anand, Elijah finds the monastery's hidden record, the Liber Silentii, a manual of containment written by monks who did not pray in the chamber below. They bound something there. The thing has a name behind the mask, and the book's first rule is not metaphor: silence is salvation. To speak is death.

As the village repeats the word and the seal weakens, the team races through ash-choked archives, iron-stained rituals, and a hunger that wants the one thing humans give away casually: permission, spoken out loud.

The Mouth of Abaddon is a monastic occult horror novel rooted in language, ritual, restraint, and containment. It follows a modern investigation that turns into a desperate operation against a cosmic entity that feeds on voice and naming, with slow dread, brutal consequences, and an ending that leaves a door ajar.
