Watchers and Angels are at war. Which side will Ember choose?
Humankind is on the precipice of the apocalypse.
As the Demons grow bolder and the walls between the planes of existence weaken, Ember is forced to develop her powers as quickly as possible, and she seeks out a powerful earth Watcher to continue her supernatural lessons. Her glimpse of the future demands she fight the dark forces spreading across the earth.
But her new mentor has his own agenda, making her question everyone and everything she ever trusted.
When Ember is thrust into the world of the Watchers, she learns of their plans-ones that defy the scripture and make them enemies of the Celestial Host. Ridding the world of evil gets complicated when it becomes impossible to take sides.
As Ember struggles with morality, she soon discovers that there's something more frightening than anything she's faced before.
