While the story concept is not new, Moore and McWilliam do a terrific job of supplying humor to a boy’s imagination.  “If you build a perfect sandcastle, a dragon will move in.” (First line in the story.)  And then the fun begins.  A young boy finds his soul-mate in his dragon as they toast marshmallows, swim, and fly kites.  It’s only when his family doesn’t believe in the dragon that the mischief starts.  The dragon becomes the scapegoat for the disappearance of all the sandwiches, blowing bubbles in the lemonade, and putting fingerprints in the brownies.  The last straw is when the dragon sprays sand all over his sister.  The castle and the dragon have to go – at least until the next day!  Is the dragon real?  Is it Dad?  Or, is it a combination?  Howard McWilliam’s hilariously expressive illustrations are perfect for this light-hearted beach tale.
