Mare Barrow's world is divided those with red and those with silver. Mare and her family are lowly Reds, destined to serve the Silver elite whose supernatural abilities make them nearly gods. When Mare accidentally discovers a power of her own she didn't know she had, the Silver king is forced to hide the impossibility of her power and pretend she's a long lost Silver princess betrothed to one of his sons.
Soon, Mare is drawn into the Silver world, where loyalty and desire can tear you apart and the only certainty is betrayal. And before long, her actions put into motion a deadly and violent dance, pitting prince against prince and Mare against her own heart.
