When Rhine is sold as a bride, she vows to do all she can to escape. Yet her husband, Linden, is hopelessly in love with her, and Rhine can't bring herself to hate him as much as she'd like to. He opens her to a magical world of wealth and illusion she never thought existed, and it almost makes it possible to ignore the clock ticking away her short life. But Rhine quickly learns that not everything in her new husband's strange world is what it seems. Her father-in-law, an eccentric doctor bent on finding the antidote, is hoarding corpses in the basement; her fellow sister wives are to be trusted one day and feared the next; and Rhine has no way to communicate to her twin brother that she is safe and alive.
Together with one of Linden's servants, Gabriel, Rhine attempts to escape just before her seventeenth birthday. But in a world that continues to spiral into anarchy, is there any hope for freedom?
