The Thirteenth Oath

By Kayla Franz

In a world where shadows breathe and oaths carry the weight of blood, one promise binds two souls in a fate darker than death.

Marienne, a commoner with striking auburn hair and eyes like green fire, has always walked the line between the living and the cursed. When tragedy draws her into the path of Lord Dorian Blackthorne-a man as dangerous as he is magnetic-her life spirals into a labyrinth of desire, secrets, and forbidden magic.

Dorian is bound by a legacy of thirteen oaths, each darker than the last. To break them is to invite ruin. To keep them is to lose what remains of his humanity. Yet when Marienne stumbles into his world, fragile but unyielding, she awakens something in him long buried-an obsession he cannot resist.

But obsession is never gentle. It consumes. It twists. And as Marienne and Dorian's bond deepens, they are forced to confront a haunting truth: love may be the most dangerous oath of all.

A gothic tale of obsession, betrayal, and passion that burns against the darkness, The Thirteenth Oath is perfect for readers who crave romance wrapped in shadow and secrets that demand sacrifice.
