When a forgotten gate to the Folk realm is discovered, Fia is tasked by the High Queen to break Eala's curse and retrieve her, and to capture a powerful magical weapon that will help humankind destroy the evil in Otherworld.

After her sacrifice on the Ember Moon, Fia is flush with powerful magic and eager to rush into battle against her murderous sister, Eala. However, Fia's new husband Irian suggests they bide their time and retreat to the Silver Isle, a snowy island at the edge of the fae world.Ruled by the cunning smith-king, the Silver Isle proves far from a safe haven. Fia and Irian become embroiled in the Tournament of Kings competing for a magical forging of immense power. Fia and Irian's relationship will be put to the test.

After the explosive finale of the Tournament of Kings, Fia and Irian manage to escape to the wildlands, dodging pursuit by Fia's cunning sister Eala. With Fia locked in her own mind, battling a powerful celestial entity, Irian must form new alliances to come up with a plan to defeat Eala's terrifying magic. With both the human and fae realm under threat, Fia and Irian must pursue their dangerous plan, no matter the cost.
