The price of power is never paid alone.
London, 1893.
Historian and archaeologist Arthur Pendelton returns from his grandfather's funeral carrying the guilt of an expedition that ended in death. What he inherits is worse than a ruined reputation: a shard of black glass, a coded confession, and evidence that his family helped build a secret institution powerful enough to erase people from history.
The shard belongs to the Obsidian Grimoire, a forbidden archive created after seven occult scholars tore open a threshold they could not close. Its magic obeys one law: every act of power demands an exchange. A recovered memory may cost another. A binding imposed on someone else leaves the binder vulnerable. Every door opens in both directions.
Now the Grimoire's scattered fragments are being hunted by the Obsidian Hand-an international order that claims to protect humanity by controlling what others are permitted to know.
Pursued from the Pyrenees to Cairo, Rome, Cambodia, and the buried ruins of Saint Orison, Arthur must work alongside scholars, assassins, custodians, and former enemies whose lives were shaped by the institution his grandfather created. But the greatest danger is not the book itself.
It is the belief that good intentions make anyone fit to decide the cost for someone else.
As an ancient presence begins moving through hidden memories and carefully buried contradictions, Arthur must choose whether to claim the Grimoire, destroy it, or surrender the private exception that has justified every boundary he has crossed.
The Obsidian Covenant is a gothic historical fantasy about forbidden knowledge, institutional power, memory, grief, and the terrible difference between protecting something and owning it.
Perfect for readers who enjoy atmospheric occult mysteries, morally complex magic systems, secret societies, historical adventure, and character-driven dark fantasy.
