Debilitada y prisionera, privada de su potente rayo y atormentada por sus errores, Mare Barrow se ha postrado a los pies de un traidor. La otrora "Niña Relámpago" vive ahora a merced del joven que alguna vez amó, Maven Calore, espurio rey de Norta, quien continúa su malévola campaña de expansión y genocidio. Pero más allá de las murallas palaciegas, la rebelión Roja crece y se multiplica; y el joven príncipe Cal, legítimo heredero del trono, hará todo lo posible por rescatar a su amada. Sangre roja y plateada correrá por pasillos y plazas.Mare Barrow is a prisoner, powerless without her lightning, tormented by her lethal mistakes. She lives at the mercy of a boy she once loved, a boy made of lies and betrayal. Now a king, Maven Calore continues weaving his dead mother's web in an attempt to maintain control over his country—and his prisoner. As Mare bears the weight of Silent Stone in the palace, her once-ragtag band of newbloods and Reds continue organizing, training, and expanding. They prepare for war, no longer able to linger in the shadows. And Cal, the exiled prince with his own claim on Mare's heart, will stop at nothing to bring her back. When blood turns on blood, and ability on ability, there may be no one left to put out the fire—leaving Norta as Mare knows it to burn all the way down.
