Now, the members of the Order must work together if they are to uncover the true enemy hiding in Bohemia. Can they work together despite their divisions? Or will their division lead to even more destruction? 
FROM THE BOOK: “How do I know you’re telling me the truth?” The last thing I wanted to do was hurt him, but if I did not find a way to break free of him, I would risk doing even more harm. 
Ferdy met my gaze with his. “I promise you this, Ella, that as of now, I will never lie to you again.” He leaned forward and kissed me again, and I stood there, letting him, desperately debating whether I could trust him or not. His promise burned through me, his words scorched into my being. It was so tempting to believe him, more tempting than anything else I had ever faced in all my life. 
Freedom was only freedom if I could trust it to be true.
