This is the 5th book of blue bloods series. After inheriting the dark Van Alen Legacy, Schuyler fled to Florence with her forbidden love, Jack. Now the two of them must embark on the mission Schuyler was destined to complete: to find and protect the five remaining gates that guard the earth from Lucifer, lord of the Silver Bloods. Back in New York, Mimi has been elected Regent of a crumbling coven. Struggling with her heartache over the loss of Kingsley and with her overwhelming desire to destroy Jack, she must focus all of her energy on a perilous new threat. Vampires are being abducted and their captors are planning to burn them alive online…for all the world to see. Help arrives in the form of Deming Chen, a Venator from Shanghai, who must untangle the web of deceptions before the killers strike again. As the young vampires struggle for the survival of the coven, they uncover a deadly secret, a truth first discovered by Schuyler’s mother during the Renaissance but kept buried for centuries. And as the Blue Blood enclave weakens yet further, fate leads Schuyler to a terrible choice that will ultimately map the heart.
