Query: This Book Rocks!

Samantha is just a simple gothic rebel, whose sister is a cheerleader with a boyfriend she loves, and to make matters worse, she has to attend drawing lessons. But then, one more even worse thing happens and she saves the president and becomes a teen ambassador. Pretty sad, huh? But wait till you hear this- The president's son just might be in love with her.I loved this book and read everything carefully. Guess what? I read this book, for like, over 10 times and never got tired of it (Yes, I'm that obsessive)! I recommend this book to people older than 12, and this book rocks!~
