Surely it must be the boy that she has spent the last month being strangely enamoured by, only to find out that he is an almost two hundred year old immortal who feeds on the life blood of other beings. But all is not as it seems, and as Zoe confronts the creature that hides behind Mercer's eyes, she will discover who the true monster is, and make a decision that will change her and Mercer's lives forever.
