Bị cha mình bán đi để trả một món nợ mà cô thậm chí không hề hay biết, Elena bị đưa đến một hòn đảo tư nhân ở Biển Bắc. Cô cứ ngỡ đó sẽ là một ngục tối, nhưng Magnus Vestergaard đã xây cho cô một chiếc lồng son làm bằng thủy tinh và lụa. Anh ta không muốn tiền bạc hay bí mật gia đình cô—anh ta muốn điều duy nhất mà cô thề sẽ không bao giờ trao đi: linh hồn của mình.
One day you are living your life, and the next, you are a piece of currency. Your father has done the unthinkable: he sold you to settle a debt you didn't even know existed. Now, you are Elena, whisked away across the freezing North Sea to a private, mist-shrouded island that belongs to one man: Magnus Vestergaard. He is known as Magnus the Merciless, a man whose heart is as cold as the waves crashing against his shores. You expected a dungeon, but Magnus has prepared something much more insidious: a gilded cage of floor-to-ceiling glass, Italian silk, and predatory grace. On this island, his cage has no bars, yet you have never felt more trapped. Magnus doesn’t want your family’s money or their corporate secrets. He wants something far more intimate, something you swore you would never surrender: your soul. In this dark captive romance, the line between hatred and desire is razor-thin. As you navigate his obsessive attention and possessive demands, you must decide if you will fight to escape or succumb to the magnetic pull of a man who refuses to let you go. This is an interactive experience like no other; with SideHop’s cutting-edge face-swap technology, you can upload your own photo and literally become the main character. See your own face in every intense encounter and every heart-pounding moment of defiance. As the secrets of the Vestergaard empire begin to unravel, you’ll find yourself questioning everything. Is Magnus the monster who stole your freedom, or is he the only one capable of truly seeing the real you? Can you survive his obsession, or will you find that the most dangerous place to be is inside his heart?
