Banished from Heaven, the angels awoke on Earth as immortals, cursed to survive on human blood and to live forever through cycles of reincarnation.

Together, Michael and Gabrielle created the Code of the Vampires, the rules that they would all follow through the centuries to bring peace and beauty to the world, with the hope to one day be forgiven and be allowed to return to Paradise.

Fallen angels who have remained loyal to Lucifer and have no desire to return to Heaven or to follow the Code, Silver Bloods each have the strength of a thousand vampires.

Instead of feeding on humans, they fed on their fellow vampires—the Blue Bloods—consuming their souls and memories; this act led to a life of turmoil and misery, and turned their blood silver.

Lawrence Van Alen, the newly appointed Regis of the Coven, must go to Rio de Janeiro to find out who is responsible for the Silver Blood menace, leaving Schuyler alone in New York.

Lawrence, Schuyler and Oliver raced to the Statue of the Redeemer which is the location of Corcovado, the prison which holds Leviathan, Lucifer's brother, to try to stop him from being freed but when they arrived they realized it was too late.

They were soon attacked by Lucifer himself when they reached the top of the mountain and in their battle, Lawrence was stabbed with a poisoned sword, destroying any possibility of future reincarnations.

She is heartbroken over losing Kingsley, who is trapped in Hell, and faces immense rage and embarrassment over Jack's decision to forsake their bond to be with the half-blood, Schuyler Van Alen.

Meanwhile, she has begun working with Oliver—an unlikely situation due to their rocky relationship—and the Lennox twins in order to find a missing teenage vampire who has been kidnapped and threatened with being burned alive.
