Impossible was a very addicting read that had a mix of romance, curses, and a fairy tale gone wrong. I loved the whole curse aspect behind the story and the three tasks that had to be completed in order to keep Lucy sane unlike the rest of her ancestors. Lucy was a very strong character that was believable most of the time. She never backed down once even when she lost all hope in completing the tasks. Which I thought was very brave of her. Also, I liked Zach's hero type of personality. I wish all guys were like him because of the way he stayed by Lucy's side throughout the story. Nancy Werlin's writing was not incredible but very close to it.
I only had a couple of small problems with the story. For one, I wished there was more of a back story to Lucy's ancestors. I would have liked to seen how their lives turned out after the curse struck them with insanity. Second, I wished their was more to the ending. I felt that it was just quickly summed up without many details of what Lucy's life was like after the outcome of what happened.
Overall, Impossible was a excellent story that I suggest to all kinds of readers. You will not be disappointed with this.
Grade: A+ as in you have to go get it now!!
