I NEVER THOUGHT A BOOK COULD CHANGE MY LIFE! My best friend has nerve. She gave me a hot new book called How to Kiss Like an Expert. Now she wants me to practice on a teddy bear--so I'll be ready for Mark! Mark is the biggest hunk in the entire seventh grade, if you ask me. And he's coming to my thirteenth birthday party! Unfortunately, so is Star--the gorgeous new girl who looks as if she could write a few expert books herself. Everyone wants to play kissing games at my party--but how can I play when I've never really kissed a boy? And what if Mark picks Star? I just hope thirteen's my lucky number...
