Query: Jaci has written a great book

This is her first book and it is really good. she talk openly about the troubles she in facing as a teenager (note: she is only 18) Jaci talks about self-esteem, dating, and her life. Some of her stories about her life are funny and will make you laugh and smile. This is one of the best book I have ever read!! :-)
