When the alien Aurai need a human bride to carry their king's heir, 18-year-old Leah Carter's father offers her up, and if she refuses, her 16-year-old sister goes instead. To save Wren, she marries Rhaekor, the cold alien king who swears his kind feels nothing. But on his world, every emotion glows on the skin, and his markings keep betraying exactly what he wants: HER. As his court plots to expose their marriage as a lie, Leah must decide whether the monster she was sold to is hiding a heart worth choosing.
