Vows Written in Ash

When bankrupt heiress Seraphina Vale is forced into an arranged marriage with Lucian Blackthorne, the reclusive duke who owns half the city’s underworld, she expects a gilded cage. Instead, she finds a mansion of locked rooms, servants who won’t meet her eyes, and a husband who touches her like a vow and threatens her like a sentence. Lucian claims he married her to settle her father’s debts, but Seraphina soon discovers her name is tied to something far older than money: a secret society that has been trading bloodlines, favors, and bodies for generations.

Lucian is not merely the monster society whispers about. He is hunting the men who destroyed his family, and Seraphina may be either the final key to his revenge or the one weakness that can ruin him. As desire becomes a battlefield and trust turns dangerous, Seraphina must decide whether to escape the darkness—or become the queen of it.
