The explosive conclusion to New York Times and USA Today bestselling author Chloe C. Peñaranda's Nytefall trilogy.

The strongest light needs the deepest shadows.

Reeling from shocking betrayal, the Star Maiden Astraea must now race against time to break the curse imprisoning her lover, Nyte. She will have to decide if the hand of darkness, or that of her enemy, is an alliance that could bring him back.

But with the loss of daylight and the realm on the brink of ruin, Astraea and her companions must set off on their quests to retrieve the Maiden’s broken key, the only weapon that can kill the wrathful gods determined to rule the mortal world.

Dragons will fly and their bonds may choose friend or foe. Gods will face gods, fathers will face sons, and all will face the end of the world. Because when the blood that binds them becomes a weapon to end them, two star-crossed lovers must yield to fate or pay their greatest sacrifice yet.
