She was sold to the devil to save her family name. Blackthorn is no ordinary devil—he wants more than her soul. They say his keep devours those who enter, so why did it let her in? When Esmeray Arden is forced into a mysterious political marriage, she expects cold halls, colder stares, and a husband who keeps secrets like dead men keep silence. What she doesn't expect is a castle that shifts when she sleeps, vanishing doors made of corpses, and mirrors that reflect what isn't there. Kael Blackthorn isn't just a reclusive lord—he's the reluctant guardian of a cursed legacy, hiding a truth that could unravel their world. Bound by rules he never explains and shadows that know her better than she knows herself, Esmeray begins to question everything. Then she finds a door that is never meant to be opened—and something ancient starts to stir. Now, the castle watches her. The halls move for her. And something beyond this world... wants her. In a world where memory fades, magic breathes, and love may be the most dangerous curse of all—Esmeray must uncover the truth before the keep claims her too.
