Gemma thought her mind was gone, but she was wrong. Now she's left trying to figure out what Stephan's planning to do with her and the star, before it’s too late. But finding out the truth is hard, especially when Gemma doesn’t know who she can trust. There may be only one person who Gemma can turn to, but that means going to the one place no one wants to go—The Underworld.
