In this epic sequel and conclusion to the Darkening duology, which has been called "enchanting and wildly clever" (Ayana Gray, New York Times bestselling author of Beasts of Prey), Vesper Vale, once savior to a city plagued by cursed storms, finds herself facing an even more sinister threat when an ominous light summoned by the Great King seizes control of the city.

Vesper Vale sacrificed everything to save her city from the cursed storm. After becoming a vessel of The Great Queen, Vesper awakes from a slumber three years after her life altering choice.

What she finds isn't a home freed from the terror of the storm, but one where its citizens are besieged by the even more sinister force of The Great King and his growing army of the lightstruck—once regular citizens who are now controlled by the ominous light encroaching on the city. And the people are all looking to Vesper, now revered as a goddess after her sacrifice, as their city's only hope.

To save the rings from the Great King, Vesper must contend with the obligations of being a deity to her people and the growing chasm between her and Dalca, the prince she swore never to love. Haunted by the guilt of their past choices and faced with the pressures of a city near ruin, Vesper and Dalca find themselves torn between the growing factions within the city and the royal court.

But in order to save her city from the light, Vesper must face the power most outside of her control—the goddess within.
