The Uncommon Reader by Alan Bennet

This is one of those rare books that you can fly through in a couple of hours and enjoy every moment.  If you are a reader (and you are, I'm sure) you like to read about other readers.  And this reader is the Queen of England.  Imagine that the Queen is just too busy to read, but then finds a bookmobile close to her castle and gets hooked.  That's the plot.  As she reads, she changes as she's exposed to the world of reading.  Fun.  -June
