TheVerge
"What if some thoughts weren't meant to be known?"
The Phantomhive Manor is recruiting a new servant. She is not at all the most respectful and devoted servant that the young Master has, but there is a purpose for her presence. She can be very bothersome and infuriating, however, she has an amazing ability that Ciel Phantomhive finds quite useful.
She can read anyone's thoughts.
No matter the person.
Her powers, as the young Master says, is the only thing that is keeping her here. If she were just plain with no powers, he wouldn't have given her a second glance.
But later in the book, where strange events that take place where the Queen is concerned, thoughts might be changed throughout struggles and hardship.
Will Ciel be her enemy, or a trustworthy friend? Will things ever change between Sebastian and Scire? Will she let her past define her? Or break out of the cage?
