The Missing Piece Meets the Big O is one book every kid should read.  The missing piece is looking for some place to fit so it can roll...any place.  It turns out, there are lots of places with a missing empty space, looking for a missing piece.  Some places are too small, some are too big.  Some fit now, but don't fit later and The Missing Piece is determined to find a place to fit.  That is, until The Missing Piece meets the Big O.  The Big O is different, because it is whole and does not have an empty space.  The Missing Piece wants to be a part of the Big O, but The Big O is already complete and can't can't carry The Missing Piece.  The Missing Piece finally figures out a way to chip at his sharp edges and roll on his own, eventually catching up with the Big O and becoming a whole piece himself.

This book sends kids the message to not only not fit in with the wrong crowd, but to find a way to be happy with themselves and make their future their own.  Perfect for anybody 3 - 99 years old.
