There Was an Old Dragon Who Swallowed a Knight by Penny Parker Klostermann illustrated by Ben Mantle*

I loved this retelling of the classic There was an Old Lady Who Swallowed a Fly!  Sometimes fractured versions of this story seem forced and contrived.
In the beginning the reader sees a knight gallantly riding his steed, not afraid of the danger that lies ahead.  The dragon proceeds to swallow him, his steed, a squire, a cook, a lady, a castle, and a moat.
I especially like the ending.  It differs from typical fractured versions of this story.
The illustrations definitely support the story and add to the story.
*Highly recommend.
