Until the World Falls Down

After a painful betrayal, twenty-eight-year-old Nell makes a desperate plea for love and offers anything in return. Her bargain is answered by Enver, a cursed immortal without memories or emotions, who brings her to his timeless castle. There she is given a choice: escape his labyrinth within forty-eight hours or remain with him as his lover forever. As Nell navigates the labyrinth and resists Enver's allure, she uncovers secrets about herself and about the being who rules the castle, and must weigh her heart against her freedom. The book is described as a dark romantasy blending elements of Labyrinth and Beauty and the Beast.
