Anna Trenton, a young woman inexplicably immune to vampire harm, has endured years of torment from a trio of sadistic vampires who culminated their cruelty by massacring her family. Haunted by guilt, she travels to Volterra, Italy, seeking her own demise at the hands of the ancient Volturi. But the notorious coven has other plans for the girl who cannot be broken.

In a celestial realm where wings denote rank and destiny is woven by the enigmatic Fate, Serenity, a young, wingless angel, yearns for her own pair. But her innocent desire becomes a pawn in a divine game when Fate tasks her with an earthly mission: to uncover why mortals are dying before their time in a place called Volterra. What awaits Serenity on Earth, and will she find her wings, or something far more dangerous, in the shadow of an ancient vampire coven?
