Bijou 

A drug made of living souls. Is immortality worth the cost?A black market in souls; their essence, known secretly as Bijou, bestows the illusion of youth to those who can afford it. Annie Novak and her family have long sought to protect the dying and the newly dead from soul-theft, but a new and unimaginable threat has appeared; someone is stealing souls from those who are not yet dead, and the distilled infusion of Bijou Xtra provides long, long life. The soulless dead are massing and very, very angry. Only Annie can stop the emerging deadly army, and save the life of her daughter, Zoe.
