This is a fun book of word play.  It might be hard to do at story time, but it could be fun in a class room setting where they are studying words.  U needs some time off from Q, so they take a break.  But it causes other letters to break up as well.  The author did a great job with all the puns and word play, I just wish they could have found a way to use Q words without the U.  They do exist.  It would have been a great way to introduce them.
