I am 16 years old right now, but i was 13 when i read the book, and i LOVE it.
What you need to know is, this book is NOT just about some girl that had sex when she was 13. Its about more than that. The story takes place when she was 16, and she has to live with all the bad decisions she has made, and tries to figure out how to make her life better, and i think that she succeeded very much. This book is very emotional and is and will always be one of my very favorites.
