Hope. Magic. Balance. The true, holiest of causes. Eighteen-year-old Gracie Caine wants to live a simple, normal life after leaving Ariel's Gate Orphanage. All she has is a photographic memory and a twisted club foot, but she feels good about herself until a shocking set of unexpected wings and a deadly war turn her hopeful future into something very different.

She has awakened to a secret world of angels and demons, bloody war and terror. It's a world unseen by humans, veiled in magic, inhabited by breathing archangels and ancient beings, and ruled by battle strategy, money, and power.

Realizing that normal will never happen for the only known surviving pure Nephilim, Gracie is set on a precarious path burdened with the duty to protect her entire race. A promise was made in the beginning and the Nephilim are failing miserably. Their end is near, generating serious danger to human beings and the planet. Gracie must deal with her own fears and limitations, the diverse elements of their race, and those who wish to destroy it in a desperate effort to regain balance between good and evil.
