For twelve years, Mira Solenne has lived as a ghost, haunting the city's underbelly as a translator of forbidden "binding-script"?the remnants of a dead language that once held the world together. She survived the night the Ashen Court burned her family to ashes for a crime they didn't commit, and she has spent every day since ensuring that no one holds enough of her to destroy her again.

That carefully constructed isolation shatters when Cassian Vey, the Warden-Commander known as the "Hound of Ash"?the very man who led the raid that destroyed her life?tracks her down in a tavern. He does not come to arrest her; he comes out of desperation. The magical border known as the Veil is failing, and the Court needs the only living soul capable of reading the language the Veil was written in.

Bound together by a fragile, distrustful truce, Mira and Cassian are forced into an uneasy partnership that defies both the Court's secrets and their own pasts. As they trace the fragments of a conspiracy that reaches the highest levels of the Court, they discover that the fire that "killed" Mira was not a tragic accident or a case of mistaken judgment, but a deliberate, forged execution orchestrated to bury an even darker secret regarding the Veil itself.

In a world where truths are rare and safety is a lie, Mira and Cassian must navigate the wreckage of their shared history. As the boundary between their world and what lies beyond it begins to collapse, they are faced with a terrifying choice: continue to hide in the shadows of their own survival, or risk everything to confront the conspiracy that threatens to unmake their world entirely.

The Hound and the Heretic is a story of long-buried grief, dangerous secrets, and an unlikely bond forged between two people who have spent a decade learning how to live among the ashes.
