She was promised to a demon before she was born.
He hadn't felt anything in three hundred years-until her.
Elara never asked to be marked. Never asked to be taken. But when her mother made a deal with the Demon Lord of the Underrealm, Elara's fate was sealed in blood.
Now, the realm trembles beneath Azrien's power-and she is his.
Cold, cruel, and inhumanly powerful, Azrien doesn't care if Elara loves him. He only cares that she lives. Because her soul was promised. Her body was made to survive him. And her heart... he'll break it before he begs for it.
But Elara is not a vessel.
She is not a pawn in anyone's game-not even the devil's.
As the realm begins to unravel and a deeper darkness stirs, Elara must decide what she's willing to sacrifice: her freedom, her fear, or the very demon who would burn eternity to keep her.
A dark fantasy romance filled with twisted bargains, brutal devotion, and an ending you won't forget. Perfect for fans of possessive monsters, morally gray men, and heroines who refuse to bow.
