This book was really well done.  It is laid out like a graphic novel.  Molly is a little girl who is afraid to speak in front of the class.  She comes up with various reasons not to, including going a full day without talking.  This day makes her realize how many people say I Can't!  But she knows they can.  And if they can, then she can!  I like that there was not some big multistep way to believe in yourself.  It was a simple idea, but one that sticks and one that works.
