 Life has been difficult for Sophie Mercer the last year. She found out that she was a witch, a dark witch, and then ultimately a demon. The guy she had a crush on turned out to be a member of The Eye - a group of people who hunt and kill Prodigium. It's been six months since she killed her psycho demon grandmother Alice, and decided to go through the process of Removal. Now, she's just waiting on her dad, the head of the Council to come and whisk her away to London so that she can go through this process. 
 But he gives her an ultimatum instead. Spend the summer with him and after that if she still wants to get rid of her powers he'll approve her decision. She agrees if she can bring her vampire friend Jenna along with her. In London, she discovers that things outside of Hecate aren't as peachy as the headmistress has made it out to be. Other than her father and herself, there are two other demon children - Daisy and Nick - and they're staying at the Council's new headquarters because The Eye burned the old one down months ago. And the Eye has teamed up again with one of the Brannicks so a war between them and the Prodigium is inevitable. Then there's also the unresolved issue of Archer Cross that she has to face when he saves her life one night. What's a girl to do?
