Jessica is the main character and I liked her as a character but I felt she didn't know what to do, what to think and what to feel. I mean if I was told I was special or to go to a certain place, I wouldnt just do it, I would think about why, what will happen etc. I felt very disconnected with her but I still no matter what liked her for her bravery and courage throughout the book.
Her grandparents are so mysterious and strange in a way I really cant explain. They were there but then they weren't. It wasn't until half way through the book that they actually became more involved in the book.
Her friends or enemies I'm not quite sure who's who, I was very confused because one minute she's friend with one person then the next they are enemies and I didn't see this happen it just did. Some friends were actually not in the book really until the end and then the storyline there was good but weird.
There is more characters but I feel I can't really say much about them.
My overall opinion is I loved the concept of the book and the ideas, but I felt it could of been set out better.
I recommend this book to younger readers, and maybe people who would read anything.
